4:53 So then 13-O-8 is electrically positive, correct? Because the net charge on both sides has to be 0. And 0-e-(-1) + 13-O-8 has to have total charge of 0. Just want to make sure.

yea trying to figure out this part also. Did the electron leave the atom entirely or did it just leave the nucleus but is still within the electron cloud of the atom?

[@Alexa-pc6ux]

@@JoeBased08 It's still in the cloud around the nucleus, so the net charge stays the same and the atom stays neutral.

I learned a bit about nuclear physics and nuclear chemistry in my modern physics class last year, but have yet to take nuclear and particle physics (I take it in the fall). Im brushing up and have a few questions, which may be a bit advanced for this lecture, but I thought I'd ask anyways. First, in electron capture and positron production, why is it that either a positron can be emitted or an electron captured during the transmutation of a proton into a neutron? I used to wonder why the proton could absorb an electron and produce a system with a positron and an electron without mutual annihilation, but then realized that the proton and neutron are both comprised of up and down quarks, which are what determine their charge. It seems then, quarks being tied together by the weak force, can in times of instability transmutate one of their quarks into either a down or an up quark to attain a more favorable balance in their system. If this is the case, is beta decay (electron emission and positron production) an electroweak interaction, whereby the quark in the respective neucleon is able to flip its charge state (+2/3 -> -1/3 or -1/3 -> +2/3) by either emitting the excess full unit of charge energy from the weak field into the electromagnetic field or from the electromagnetic field into the weak field? Is the electron emitted in beta decay emitted into the s1 orbital and the kinetic energy conserved through a sort of consecutive jostling of electrons into higher orbitals until an electron in the outer shell ejected? Why doesnt a positron emitted during beta decay annihilate with an electron in one of the energy shells and produce gamma radiation rather than an ejected positron? In that same token, if one were to fire a stream of positrons into an oncoming stream of neutrons (from a neutron source with sufficient flux to induce a non negligible probability of collision), would the positron and one of the down quarks combine to produce a proton (in much the same way as electron capture)? Obviously, such an interaction cannot happen (or is very improbably to happen) within the nucleus of an atom since the electrons orbiting it preclude the existence of positrons and the net positive charge of the nucleus would repel any incident positrons hurdling towards it. Or does beta decay require that the absorbtion and emission of electrons and positrons occur only when the strong field is in a state of instability or meta stability such that the interaction becomes energetically favorable (precluding lone neutrons from capturing incident positrons and undergoing beta decay into a proton and neutrino)? Lastly, also beyond the scope of this video, does the capture of an electron produce the emission of a neutrino in order to balance the lepton number of the atom? Is an atom with too many neutrons more likely to undergo electron emission while an atom with too many protons more likely to undergo positron emission and electron capture? I'm completely fascinated by nuclear chemistry and nuclear physics.

Great explanation. I was struggling to understand why there is negative sign in beta particle and how it increase atomic number of products

[@pianoslayer2516]

Do we have any direct observation of an unstable element changing into a different element? My understanding is that an unstable nucleus has a probability of spontaneously decaying and emitting radiation. The idea being that if, say, the atom underwent alpha-decay, its nucleus would change. Is there any evidence of the actual sample changing from one element into another?

Hold up in the previous example, when when Nitrogen-13 reacted with a beta particle the number of protons increased to 8. But when Arsenic-73 reacts with a beta, the number of protons go down from 33 to 32???

[@izzzher]

this is late but for anyone stuck... the Arsenic is an example of electron capture whereas, nitrogen is an example of beta decay. in electron capture, the nucleus captured an electron from the inner core resulting in the lowering from 33-32 even tho set up looks like the same the processes are different. hope tht helps.

[@santamaria1363]

This is a great video, thank you. I have a question. When you are just given an element, like 99/42 Mo, that is mass number 99 and atomic number 42, and you are asked to give the product and decay sequence assuming via alpha, electron, positron, and gamma, how will you go about it? I just want to understand properly. Thank you.

[@maxinyepez7516]

I'm not sure but I think its like these alpha 99/42 Mo -> 4/2 He + 95/40 Zr beta 99/42 Mo -> 0/-1 e + 99/43 Tc positron 99/42 Mo -> 0/+1 e + 99/41 Nb gamma 99/42 Mo -> 0/0 + 99/42 Mo

[@yoursleepparalysisdemon1828]

3:12 im confused, does beta decay add to Z at the bottom left? I thought that number at the bottom left was nuetrons specifically. Because an electron is lost, no weight changes, therefore there are the same amount of protons. How can it be a higher element?

[@deliciousnutritious6805]

The number on the bottom left is the number of protons, or in other words the atomic number. In chemical equations, you must have all protons and mass numbers accounted for. The beta decay means that you have to find a greater atom than Nitrogen's, because the sum would have to equal to 7.

[@esorse]

As long as a subatomic configuration of neutrons, N, electrons and protons, Z, has a non-negative half life - the time remaining for half of the sample to fully decay - , the electron and neutron cannot have opposite charges, but they could have "e" and "p" charges respectively, A - N = Z ≡ p = e * . * Atomic mass.
