Since valence electrons are those in the most outer shell of any element, I would say you chose the correct one!

Yay! I thought so but for some reason, I was thinking Na, Sodium, because I couldn't remember if it had 1 or 2 valence electrons, but I'm pretty sure it only has one... Thanks for your help!

Electrons repel each other, since they have like charges. You put them in different orbitals if at all possible, since that keeps them naturally further apart, and lowers the energy of the electron configuration. You only start doubling them up when you must.
