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.

Copper is a non metal element. There are 29 electrons in a single atom.
the first ring has two second has ten and third has eight
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.
Boron has three electrons in its outer shell
Boron has 5 electrons per atom. Boron's electron configuration is 1s2 2s2 2p1. Thus, it has 3 electrons in its outer shell.
Boron has 3 electrons in the outer shell and 2 electrons in the inner.
There are three valance electrons. These are the electrons in the outer shell if it is not full.
Boron has 2 orbitals
Phosphorus has 10 more electrons. A neutral atom of phosphorus has 15 electrons, 3 in the outer 3p shell There are 5 electrons in a neutral atom of boron, 1 in the outer 2p shell.
3 valence electronsThere are three valance electrons. These are the electrons in the outer shell if it is not full.
3, the electron configuration of Boron is 1s2 2s2 2p1, so there are 3 in the outer shell.
Boron has 3 electrons in it's outer level.
Calcium has two electrons in the outer shell.
Vanadium has on the outer shell two electrons.
Nitrogen has five electrons in its outer shell and bromine has seven in its outer shell.
