I’m pretty sure it’s protons that count for the atomic number, but I should double-check my notes.

I think the atomic number is determined by the number of protons, but I’m not 100% sure.

I'm pretty confident the atomic number is determined by the number of protons in the nucleus. That's one of the key facts we've covered in this unit, so I'm going with B, Proton.

Wait, I'm confused. I thought the atomic number was based on the number of electrons, not protons. This is tripping me up a bit. I'll have to review my notes to be sure.
NO

Okay, I've got this. The atomic number is the number of protons in the nucleus of an atom. So the correct answer must be B, Proton.

Hmm, I'm a little unsure about this one. I know the atomic number has something to do with the particles in the atom, but I can't remember if it's protons, neutrons, or electrons. I'll have to think this through carefully.

Communication plans could also be a good option, as they often outline the notification process. But the incident response policy feels like the most direct and comprehensive source for this information.

Protons, duh! If you can't count those, how will you know how many electrons to draw in the Bohr model?
