What is an atom | Matter | Physics | FuseSchool
Atoms are tiny particles that are so small they are not possible to see with the naked eye, and are only barely possible to make out with the most powerful microscopes. Everything that exists in our universe is made up of atoms - including you, I and the device you’re watching this on! In fact, there are about 7 billion billion billion atoms in your body alone.
In this video we are going to look at what atoms are made of, and the mass and size of atoms, and the arrangement of electrons in an atom.Atoms may be tiny particles themselves but they are made of even smaller particles, called subatomic particles.
Atoms consist of a central nucleus that contains protons and neutrons. Protons are positively charged (+1) and neutrons have no charge. This makes the nucleus overall positively charged.
Much like how the sun has planets orbiting it, the nucleus has electrons orbiting. Electrons have a negative charge (-1). Because electrons are negatively charged and the nucleus is positively charged, they are electrostatically attracted to each other, like how gravity ensures attraction between planets and the sun.
So that’s the general structure of an atom, what about its mass and size? Protons and neutrons have the same mass, but electrons are so small they weigh almost nothing in comparison to protons and neutrons. In fact they are about 2000 times lighter. As a result, the mass of an atom is concentrated at its nucleus.
So that’s the mass of an atom, but what about it’s size? One way to describe the size of an atom is its radius. The radius of an atoms is the distance from its centre, where the nucleus is, to the outermost shell of electrons. The radius of an atom is typically 10-10m.
So the majority of the mass of an atom is contained in its nucleus, but in terms of size the nucleus is much smaller than the atom as a whole. In fact, electrons can orbit really far away from the nucleus. If the atom was the size of a sports arena, the nucleus could be the size of a pea in the middle!
Let’s finish off by looking at the electrons in a little more detail.
Negatively charged electrons orbit around the positive nucleus in specific orbits or shells. Different atoms have different numbers of shells (or orbitals).
Each shell is of a specific energy level, meaning an electron must possess a certain amount of energy to reside in a certain shell. Electrons in shells closest to the nucleus have the least energy, and electrons in the outermost shells have the highest energy levels.
In other words, electrons orbit the nucleus similar to how planets orbit the sun; however, electrons can only orbit at specific distances and with specific energies.
We will look at the differences in structure of atoms of different elements and the periodic table in this video
So there we have the structure of an atom. Atoms have a positively charged nucleus made up on positive protons and neutral neutrons, which is orbited by negatively charged electrons. The majority of the mass of an atom [10-23g] is found in the nucleus, and the typical size of atoms is 10-10m.

I’m in middle school and my teacher expects me to understand the text in my school book, when the school book has this “special” method of teaching topics with questions. 70% of the lessons are questions. And to answer the questions, you need to have special equipment(the equipments are at school and collecting dust, as always, because the teacher never uses them). You can’t just imagine things that make sense when you have no visuals. Sad that I can’t go to my tutor. I got my hands on the teachers’ book that was given only to physics teachers(my tutor gave it to me before things went down). That book has answers to all the questions and is more helpful than the students’ version. I just wish they could stop with these “special” methods, like bitch- not everyone is born a genius. It’s bad enough already when your teacher explained gravity by dropping the pen on her desk a year ago(she did that 6-or-so times for different topics. Is that like a thing for physics teachers?)

Dear young student, the points you raise are valid, perhaps the teachers you refer to have forgotten that teaching is a vocation & not a job like a taxi driver, picking someone up at one point & dropping them off at some predetermined destination before taking the fare, forgetting about it & moving onto to the next job. I think you will do alright for yourself. Some teachers can be a handicap to their students in my experience. All the best in these strange times, an old teacher.

If here for school here are some notes from this. Protons are + charged neutrons are neutral electrons are - charged the nucleus is protons and neutrons. Protons and neutrons attract. Electrons stay away from them Protons and neutrons have the same mass and electrons are way smaller than them Electrons are 2k times lighter than protons and neutrons. The majority of an atoms mass is the Nucleus

The song… maybe you could use another song?? …
i have a theory! why atom are like. 1st we need to adapt the theory of nicola tesla " 3 , 6 and 9 " are supposed to be the key to universe. Now we take " 3 " as the cold state. 9 as the hot state and 6 as the in between. there are 3 distinctive atomic features in reality. The hard, the soft and the air. Now stones are made of atoms so they are hard. the water are soft. the air are airy. if the nucleus is standard state or permanent the sub-atomic particles could be either of the 3 distinctive features. then the theory of nicola tesla can determine if the nucleus can go to a...... i forgot sorry. i've taken the i.q test then this theory just went in a flash. maybe i will remember this soon. thank you.

Hello fellow park view students ?
Neutrons are not neutral at all. Having too many neutrons within an unstable nucleus of a radioisotope will cause one or more neutrons to undergo beta emission by emitting out energetic electrons before it itself turning into a proton. If neutrons are neutral, then having too many of them within an unstable nucleus will not threaten its stability at all. Wrong! Neutrons are more massive than protons due to their additional rest electrons that embedded at the tip of a "proton". Every nucleon is a tiny charged particle as well as a tiny magnet; therefore when they clustered together to form a nucleus where the electric charge and magnetic field of its nucleons will superpose to form a mosaic of elastic electric field and magnetic field that allowing stationary electrons to surf on top of it. Therefore at any ambient temperature, an atom has only one electron-shell. If rigid concept of valence shell were right then an atom will have almost similar atomic size before and after chemical reaction. Wrong! An atom will have different atomic size before and after chemical reaction. This is because nucleus is not just contains protons and neutrons but also stationary photons where photons will be absorbed or dissipated during chemical reaction in which changes in stockpile of stationary photons within the nucleus due to chemical reaction will cause nucleus structure to flex differently before and after chemical reaction. Basically there are two types of chemical reactions, exothermic and endothermic. Changes to stockpile of stationary photons onto nucleons will cause nucleus structure to flex differently before and after chemical reaction that leading to changes to its electron-shell's size and shape as well as its orbitals' orientations and configurations. Therefore an atom will have different chemical characteristics before and after chemical reaction. If you are interested in real discoveries, I would recommend you to read my book, The Unification Theory = Volume One and you will be amazed with lots of new, interesting discoveries. In God I trust.

Paradoxes of atomism If it were possible to continue the division of matter indefinitely, I would have thought it more probable that this process could be carried out to infinity (thesis of infinite divisibility, contrary to atomistic antithesis). The problem is that we can not and do not have the colossal force to do this, because we are physically limited, we can only at most split up to a few fractions of sand, because we can not get the pieces too small to be divided again and so on , only the cosmic forces of the universe could make or a God out of infinite power. It results in unsustainable paradoxes and absurdities to defend the thesis of the existence of indivisible material entities / elements, the atoms, as they considered Democritus and Leucippus, a thesis that Aristotle correctly rejected. Why do we have to accept the existence of atoms if experience shows us that all compound bodies are divisible indefinitely to our last tactile-sensitive limits? If all the material elements are breakable into smaller parts, from the softest to the hardest, an iron bar when we hit it kneads and looses small pieces of metal and sparks of fire - energy, revealing its divisibility to us, why then do we have to to accept that atoms (indivisible fragments of matter) exist? This atomistic thesis leads us to the paradox well demonstrated by Anaxagoras and Aristotle, that the parts are greater than the sum of the whole, for the components of the self are indivisible and not eternal. The results are the only and most perfect to be realized in all corpus of corruptible and mortal, which results in the refutation of atomism by reduction to the absurd. Another paradox reveals itself is not a fact of existing atoms but is not necessarily indivisible, it is not necessary to prepare an atom for its existence, for who can be indivisible, the ultimate of existence, eternal, indestructible, immune to all sorts of shocks and destructions. Existing and eternal exist, to probe and to separate the various clusters in concentrated points without space, resulting in an inexistence of cohesion / physical concretion and consequent non-existence of visualizing the bodies and material bodies! In what results in a further logical - qualitative refutation of atomism, by a new reduction to the absurd. And finally, indivisible and eternal atoms unite with other equally indivisible and eternal atoms, through connections made of finite and divisible matter as is our physical - corporeal composition and that of all the animate and inanimate bodies of the world, is an absurd total in this thesis, for where would arise a divisible and finite matter that binds atoms, if these same atoms are all indivisible, eternal and indestructible particles? Of the very primordial atoms that gave birth to the whole universe? But would a finite and divisible matter arising from indivisible and eternal atoms not be an unacceptable corruption of the eternal and indivisible essence of atoms? An indivisible atom that gives rise to a divisible matter would not have to possess the germ of divisibility in its essence, revealing in the truth that it is no atom, but a corruptible and perfectly divisible matter, which would refute the very Democritean thesis of existence of atoms? Do you perceive so much of metaphysical absurdities, paradoxes, and idiosyncrasies that the theory of atoms has borne since over 2600 years ago? In the antithesis to the atomist theory, we can not observe and test the process of division ad infinitum, because obviously we have spatial and physical - temporal limits, but at least it is indirectly based on ordinary experience, being a much more rational and scientific hypothesis than considering the hypothesis of finite divisibility in final and eternal atoms, for we have no example of phenomenon or object observable in experience that is indivisible, indestructible, incorruptible, and eternal, whereas for the philosophical hypothesis of indefinite or infinite divisibility we have the support of a sensory experience that all objects, bodies and physical phenomena are divisible or decomposable into smaller, corruptible and destructible parts!
