Nitrogen does not lose or gain electrons. It is a diatomic molecule (N2) and is a molecular compound which has covalent bonding. In other words, the molecule has a triple bond, in which 6 electrons are shared, three for each atom.
In the ground state, it has 82 electrons. It usually only shares two of those electrons into an ionic bond.
The Halogen family.All but one of the halogens are nonmetals, and all share similar properties. A halogen atom has 7 valence electrons and typically gains or shares one electron when it reacts.Hope this helped.
needed to give it to a noble gas arrangement
Elements in the same family, or group will contain the same number of valence electrons and have many similar characteristics.
"Shares electrons" is a characteristic of covalent bonds, which form covalent compounds.
Everything down the 2nd column (group) on the periodic table of elements. E.g. Be (berrylium), Mg (magnesium), Ca (calcium) and so on. When they "react", its because they either lose or gain or share their valance electrons. This is either ionic or covalent bonding. Ionic bonding is when an atom "loses" one or more valance electrons to another atom. Covalent bonding is when two or more atoms "share" valance electrons. All atoms can do this, apart from the ones in the 18th group. These are called "inert gases" or "noble gases." They have full valence electron shells. The other elements only react with one another to lose or gain electrons, to form a full valance shell. Noble gases are ones like He (helium), Ne (neon) and Ar (argon).
IT gains, looses, or shares outer electrons.
