These two isotopes differ in the number of what? electrons, protons, protons, carbon atoms or ionic bonds.
00:14
Okay, so an isotope means that they have the same element, same element, and that means a same atomic number, but a different atomic weight.
00:27
So if we have a look at these, we have carbon, 12.
00:33
And carbon 14.
00:37
So that's carbon 12.
00:39
This is carbon, oops, 14.
00:45
And they have different molecular weights.
00:48
So first of all, the six.
00:52
The six is referring to their atomic number.
00:55
And this is their number of protons.
01:02
Atomic number, which is the number of protons.
01:06
And the number of protons determines what elements you're looking at.
01:10
So they have the same elements because they have the same number of protons.
01:13
So it's not b.
01:14
Okay, now let's look at electrons.
01:17
So an uncharged, an uncharged will have the same number of protons and electrons.
01:26
Then if you have an extra, it goes to minus one charge.
01:29
If you have one less, it goes to plus one charge...
