There are three electrons in boron's outer energy level.
The electron configuration of argon is [Ne] 3s2 3p6. From this, we can see that the outer shell contains eight electrons.

Covalent bonds, free electrons, etc. Materials with strong covalent bonds do not readily share electrons and thus have very little electron movement or resistance. We need, to our understanding, electron movement in order to conduct electricity effectively at normal temperatures. We aren't talking superconductors here. Free electrons in a material such as copper allow a low resistance to electrical flow. There is also a consideration as to the number of shells of an element and the resultant attraction between the nucleus and the electrons in the outer shell, i.e., the more electrons an element has the more shells and the further away those free electrons are from the nucleus. Copper and iron have four shells with one electron in the outer shell...good. Silver has five shells with one electron in the outer shell...better. Gold and platinum have six shells with one electron in the outer shell...best. Tungsten has six shells, two electrons in the outershell...notable resistance. Lead has six shells, but four electrons in the outer shell...getting more resistive. There are many other examples for each type of metal.
