Here we are again, and we've got our protons and our neutrons drawn in.
00:06
Just like with the previous problem, there are no particles other than protons and neutrons.
00:13
There's no electrons or betas or anything like that.
00:16
Now, this guy over on the right hand side, the combination of two protons and two neutrons, is considered an alpha particle.
00:28
All right.
00:28
But apart from that, but an alpha particle in and of itself isn't like something new, like a beta particle is like a super, you know, electrify or energy, large energy electron.
00:40
A positron is a positive electron.
00:42
Alpha particle is still something normal.
00:44
It's just made of protons and neutrons, something you're already used to.
00:47
Okay.
00:48
So that means that we can apply the rule that the total number of protons on the left has to equal that on the right...
