Hi, I'm Robin Higgins and this is how does the nucleus of neon-20 differ from the nucleus of neon-22. Alright so let's lay out what we are really talking about here. We've got neon-20 and neon-22. So these numbers here are isotope numbers and they both determine the number of protons plus the number of neutrons in each atom and so neon is atomic number 10. So this means no matter what, neon is going to have 10 protons. So using some subtraction, neon-20 will have 10 neutrons and neon-22 still has to have 10 protons because it's still a neon, will have 12 neutrons. So this is the big difference on how the nucleus's differ. So if we're going to draw the nucleus of neon-20 it will be one, two, three, four, five, six, seven, eight, nine, ten protons. So give these guys each a positive charge and then it's also going to have ten neutrons so one, two, three, four, five, six, seven, eight, nine, ten. This is the nucleus of neon-20 and over here it's going to be the same thing with the protons, one, two, three, four, five, six, seven, eight, nine, ten. Each has a positive charge and we're not talking about overall charge here, we don't really know how many electrons any of these has. And then now we're going to add 12 neutrons so one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve. So there you have it, neon-20, neon-22. I'm Robin Higgins and this is how does the nucleus of neon-20 differ from the nucleus of neon-22.
