So for this question, you're asked to draw a nucleus based on a specific number of neutrons and protons.
00:08
So one thing to keep in mind when you're drawing a nucleus is that the neutrons and the protons are going to be in its tightly held nucleus.
00:15
So you're going to try to draw in as smallest ball as possible.
00:19
And then try to do neutron and proton every other.
00:24
But sometimes that's not positive, so just do the best you can.
00:27
So for the first one, we have two protons and one neutron.
00:32
So we could have our neutron in the middle, and then we have our two protons next to it.
00:40
Next, we have two protons and four neutrons.
00:44
So we could have our two protons and then our four neutrons around it.
00:52
Next, we have four protons and three neutrons.
00:57
So we can do...
