PLZ HELP ME OUT QUICKLY IM TAKING A TEST AND I DONT UNDERSTAND THIS ThANK YOU SO MUCH

I think carbon?

I could be wrong.

because the two particles have an equal charge, the charges will cancel out and give the atom an overall charge of 0. so, if at atom has 35 protons in the nucleus, we could expect it to have 35 electrons orbiting that nucleus.
