electron can be captured by proton and converted into neutron. plus gamma radiation - Electron capture

Excellent explanation. Clearly delivered, clears up common misconceptions, and uses the right tools to explain the situation. One question - wouldn't the quarks inside the protons and neutrons have the same amount of uncertainty? How do they stay relatively stationary - is that where the strong force enters the equation?

Protons and neturons do have uncertainty but that is very negligible compared to the uncertainty of electrons as they are more massive hence more momentum The strong force probably arises from gluon interaction between the two I'm not sure about uncertainty principle acting in

I thought I would never understand this but Oh My Gosh!

Nice! But in a wave packet sense the probability of the electon to be very near the center of nucleus is practically zero, and this analysis takes the Fourier transform (wave length vs. wave frequency) that is at the heart of Heisenberg uncertainty principle.

@@yasharthpandey3928 I see. Here you could add the fact that if an electron really spirals into the nucleus, then it would emit an infinitely amount of energy and that makes no sense (just like the collapse of our world makes no sense). Also, we must assume that the much heavier nucleus (proton; circa 1800 electron mass) is not moving at all in our coordicate system since otherwise we can't apply the uncertainty principle. Anyway, the minimum of classical Coulomb potential energy causes a definite location (i.e. Δx=0) and that is against the Heisenberg's uncertainty principle that is a deep law of nature. In fact, the whole quantum mechanics is based on statistical classical mechanics and uncertainty principle. Note also, the argument of the absurs speed of "5.3*10^10 m/s" is irrelevant since we are talking about a quantity that we don't know, hence the uncertainty.

Electrons can't "fall" because they are not objects. We teach this in high school, by the way. Remember your lesson on the photoelectric effect when we taught you that photons were merely small amounts of energy? Well, that's what electrons are as well.

dude u cleared my doubt in an instant! Thank you! Your teaching style is very unique!

Sir can we separate the nucleus from the atom and put it in one place?

Then how does electron capture occurs in atoms like beryllium 7, carbon 11 and other unstable nucleus with more proton than neutron yet having small nuclear size at the range of 10^-15

@lepidoptera9337

It occurs because there is enough electromagnetic energy in these proton rich nuclei to allow the conversion of a proton to a neutron and the loss of an anti-electron neutrino. That's undergrad physics. Don't bother. The kid won't get it. ;-)

Bro could you explain the sub shell and shelk and orbital beacuse theses are winthin shell and its hard to imagine it and get proper understanding beacuse this quantum modek is different from normal one

Thank you for the explanation. But still, I have some doubts. Why can't the speed of electrons be faster than light? Secondly, why the position is not fixed? I know the heisenberg's principle but why so?

@MicrowaveOvenVideo

Electrons have mass; therefore, they would need infinite energy to go the speed of light, let alone faster. They aren't fixed because they have energy, as does anything that exists, therefore they have motion.

Great!!!!!!!

@karadegautam7508

When you use the heisenberg's uncertainty principle to find out the speed of the electron in a nucleus you will find that, its speed will be far greater than the speed of light. If its speed is greater than the speed of light, then it is breaking the laws of nature

An electron revolving around proton produces some field... This field should repel other electrons around it. But no of protons decides thr no of electrons... And as a result the distance of electrons in the outer shell vecoms very large... where the force of proton dosent exists..... So Actually there are invisible forces which binds the lectons and protons together. What are these firces.

If you do and your teacher knows physics, then he will fail you. It's the wrong answer. ;-)

You just got an F in undergrad physics. The uncertainty relation is NOT the reason why atoms are stable. Lepton number conservation and the fact that neutrons are heavier than protons are the reasons. Next time please try to learn from a professional physics textbook instead of the internet. Pretty much everything you have seen about physics on the internet is either 100% false or borderline false.

Interesting but the explanation still hides behind the math, statistics in this case. I so agree that the electron can collapse only so far until the physical barrier created by the nucleus prevents the electron from going any further. So where does the electron go? It probably gets bounced back somewhere on a stable orbital. It’s specific location can only be guessed at via statistics. If there are too many electrons in a given orbital, the electrons become a barrier to each other and hence another orbital is required.

I did not get it so you said that the elctron must be so small than it has to run faster than speed or ligth?

It can't be in the nucleus because then we would know almost exactly where it is. And according to Heisenbergs principle, if we know almost exactly where it is, its momentum will be close to infinity (which is impossible).

So you're saying that because it violates the Heisenberg principle , so it can't fall. That's not an acceptable answer. Just assume for a second that the Heisenberg principle is wrong . Now ask how we will explain this phenomenon now without the Heisenberg principle.

your statement is not scientific at all. Your assumsion is that Heisenberg principle could wrong. Science is about explanation of natural phenomenon. You did not explain the mechanism of how Heisenberg principle could be wrong. So if you want to bring any possibility of this video is wrong, then first you must bring your hard piece of work that prove Heisenberg principle "could" wrong. Just bringing "what if" without any supporting it's background is not science. It's philosophy. And your supporting statement of your "what if" should be with metric. then your statement can be scientific.

Heisenberg didn't just pull the exclusion principle out of his ass; there is a sound physical and mathematical basis for it. Here is a simplified proof of it: www.phys.ufl.edu/courses/phy4604/fall18/uncertaintyproof.pdf To just "assume" it is wrong would require you to also assume that dozens of other tenets of QM that led to it are also wrong. Explaining all of the aforementioned things, either assuming they're wrong or right, would be well outside the scope of this video. So, yes, using the exclusion principle as a postulate in this video is an acceptable answer, because it expects that you have an understanding of what the principle is and _why_ it exists.

@karadegautam7508

Bro heisenberg's principle here is just used to know the speed and it isn't violating the principle it is violating the laws of nature as nothing can go faster than speed of light if it does it would require infinite energy. And heisenberg's principle is absolutely correct.

You basically said the math model dosent work when it does that which is a terrible argument
