In a reaction u need two valence electrons to gain or share two valence electrons.
not 8
Covalent bonds are formed by sharing electrons of the valence shell.
Valence electrons occur in the outermost shells of an atom. Valence electrons can be shared in covalent bonds. Covalent bonds occur between non-metals, like Carbon and Nitrogen.
Molecules or covalent compounds are formed by the sharing of valence electrons.
the valence electrons are shared.
valence electrons are shared in covalent bonding
Probably oxygen (it is the most common oxidant available in most environments).
valence electrons are the electrons located in the outer shell of an atom which are available for reaction
While forming a covalent bond, valence electrons are shared.
Through covalent bonding, the nitrogen atom will have 8 valence electrons, the hydrogen atoms will each have 2 valence electrons, and the chlorine atom will have 8 valence electrons.

Covalent bond :)
