each atom in the covalent bond is donating 1 electron. so a single covalent bond is 2 electrons.

Easier than using the Bohr model. The pair of dots between the symbols identifies a covalent bond.
IONIC BOND: The compound formed by completely transporting an electron or a number of electrons is called an ionic compound, and the bond between the elements of the compound is called the ionic bond. EXAMPLE: NaCl is an ionic compound in which the Na atom donates 1 electron to Cl atom to attain stability and thereby to form the compound NaCl. In ionic bond, generally the metals are the electron donors and the nonmetals are the electron acceptors COVALENT BOND: The bond formed by sharing pair(s) of electrons is called covalent bond. In this type of compound, each of the atom shares equal no. of electrons in order to attain stability. A covalent bond can be of three types: single covalent bond, where 1 pair of electrons is shared between the atoms; double covalent bonds, where 2 pairs of electrons are shared; and triple covalent bond, where 3 pairs of electrons are shared.EXAMPLE:N2 molecule is formed by sharing of 3 pairs of electrons, thereby forming a N-N triple bond

The number of electron pairs determines the type of hybridization between atoms. A single bond is sp, while double is sp2, and triple is sp3.

bonding electrons are when the electron have the same number and the connect,like valence electrons. Non-bonding electrons are only possible when an atom is unstable, no more than 2 electrons or if the atom is an isotope. bonding electron pairs occur in a covalent bond between two atoms. they include one electron from each atom in the covalent bond. non-bonding pairs do not take part in bonding. they are the left over electrons in the outter shell of the atom.
The proton number within the nucleus remains the same.
Nitrogen is diatomic because it can form three covalent bonds between two nitrogen atoms; this is a function of the orbital structure and the number of electrons which allows the third covalent bond to form in the same direction. In contrast, phosphorus has many more electrons than nitrogen and is unable to form three covalent bonds with one other atom - the electron orbitals get in the way and mechanically/electrostatically prevent the third bond from forming. Therefore, pure elemental phosphorus must make sufficient bonds between several atoms rather than just between two.
Br typically gains one electron to achieve a stable electron configuration, rather than losing electrons.
