8 electrons
No. Valence electrons are the electrons in the outer most orbit (or energy level) and not in outer most orbital.
an atom's outer energy level doesn't have the maximum number of electrons.

yes.they have the maximum number of electrons in their outer energy level?
Boron has 3 electrons in it's outer level.
