Groups of the periodic table | Periodic table | Chemistry | Khan Academy
Keep going! Check out the next lesson and practice what you’re learning:
www.khanacademy.org/science/b...
The s-, p-, and d-block elements of the periodic table are arranged into 18 numbered columns, or groups. The elements in each group have the same number of valence electrons. As a result, elements in the same group often display similar properties and reactivity. View more lessons or practice this subject at www.khanacademy.org/science/c...

What principle is that, and where would I find it, also why would it place the electrons in orbits without filling out the area before going to the next orbital region?
I believe that by now we have the elements Nihonium (Nh, 113), Moscovium (Mc, 115), Tenessine (Ts, 117), and Oganesson (Og, 118)
Isn't post transition metals and transitional metals on periodic table?
If groups 8, 9, and 10 have the same amount of valence electrons - namely 8, why are they not grouped as one? What properties differentiates groups (families) 8, 9, and 10 - if valence electrons do not doffer those three families (also called "VIIIB")?

what are the similar properties per each group that specifies each corresponding column?
I'm still confused which element has the highest electronegativity in the alkali metals, coz google says its flourine but flourine is a non metal element

A valence electron is an electron on the outermost shell of an atom. So No, Helium wouldn't have 18 Valence Electrons.
If you don't understand this video then you don't know the basics of electronic configuration using the 1s2 notation
why is helium in group 18 but its valence electron is only 2 ??

its first shell is complete (first shell can only have 2 electrons) and it doesnt have any other shells
@NushratNur
Жыл бұрын
Helium, having one shell and that being it's outermost shell, has 2 shells. Atoms need 2,8,18 electrons consecutively for every shell to be stable. As it has the needed 2 electrons for shell K, it has no room for donating or receiving electrons, making it incapable of reaction. This incapability for forming bonds makes an element inert.
