We're given five nuclear equations, each missing one substance.
00:05
I'll do these in order.
00:08
We are also given a list of possibilities that will fit into our blanks.
00:26
And these are numbered.
00:30
Okay.
00:38
Okay, 6 -3 lithium, 4 -2, alpha particle, 3 -1 hydrogen.
00:43
So the particle that's going to go here will be 0 and 1.
00:50
And that is f from the list.
00:59
And if you'll check this out, 6 plus 1 is 7, 4 plus 3 is 7.
01:07
3 plus 0 is 3, 2 plus 1 is 3.
01:14
Our second is gold.
01:22
And my product is 175 over 79, 77 indian, plus, and my particle here will be a 4 and a 2.
01:43
This will be alpha radiation.
01:49
And my alpha is a.
01:53
My third equation is 2412 magnesium plus a neutron.
02:08
And we have a particle plus 2411 sodium.
02:23
So this will be 0 plus 1 and e 2412.
02:37
Oh, that's a 25, my bad...
