choose two types of regions we have studied. what do they have in common? how
are they different? you should write one paragraph showing what they have in
common, and one paragraph showing how they are different.

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.
