So in this video, we're gonna talk about question 64 from chapter two, which says for carbon 14 and carbon 12.
00:08
How many protons and neutrons are in each nucleus? assuming neutral atoms.
00:13
How many electrons? air president in an atom of carbon 14.
00:18
And in an atom of carbon 12.
00:20
Um, so carbon.
00:23
So carbon 14 and carbon 12 are isotopes of each other s.
00:28
Oh, there, two isotopes of carbon.
00:30
So isotopes are atoms that have the same number of protons but different numbers of neutrons.
00:36
So the number of protons gives us the atomic number that tells us which element we have.
00:42
Um and, um, we, um the number of neutrons, plus the number of protons that's going to give us what's called our mass number.
00:51
So, um, so isotopes have the same number of protons...
