a) There are 19 electrons in a potassium atom. I don't really know how to explain it. I've been told that the number of protons and electrons are the same.

b) There are two electrons on the first shell, 8 on the second, 8 on the third, and 1 one on the fourth shell, which totals 19.

c) There is one electron in the valence shell.

d) I don't know what to do for this one. Sorry.
