The outer shell (N=4) of the copper element has 2 electrons.
Hydrogen has only one valence electrons.
Berkelium has two electrons on the outer shell.
They have 8 electrons on the outermost shell, also known as valence.

No it doesn't... Aluminum has 3 extra electrons in the outer shell

7 electrons are on the outer (valence) shells of all halogens
Beryllium has one outer electron shell with two electrons.
Hydrogen has only one valence electrons.

Berkelium has two electrons on the outer shell.
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.
Copper is a non metal element. There are 29 electrons in a single atom.
They have 8 electrons on the outermost shell, also known as valence.
Chromium has two electrons in the outer most shell.
