In this video, we're going to be talking about a type of radioactive decay, particularly positron emission.
00:13
So in this process, what happens is we have a nucleus, right, with a lot of protons, with a lot of neutrons.
00:19
And one of the protons in this nucleus in positron emission is going to become a neutron.
00:27
And how this happens is this proton is going to emit something called a positron.
00:34
So a positron particle, which for simplification purposes, i'd just like to think of it as an electron with an opposite charge.
00:44
So an electron has a negative charge, a positron has a positive charge.
00:51
And then the general formula notation for this type of reaction, we have an atom with a mass number x, and then atomic numbers to the number of proton z.
01:01
It's going to emit a positron particle.
01:08
And then the new atom that we're left with has the same mass number, right? because the proton just becomes a neutron.
01:18
But the atomic number is going to decrease by one because we lost a proton, which became a neutron...
