Covalent bonding includes many kinds of interaction, including σ-bonding, π-bonding, metal-to-metal bonding, agostic interactions, and three-center two-electron bonds. The term covalent bond dates from 1939. The prefix co- means jointly, associated in action, partnered to a lesser degree, etc.; thus a "co-valent bond", in essence, means that the atoms share "valence".

1.electronegativity of elements must be high
2.the ionization energy of elements must be high.
nitrogen created greater number of covalent bond
the sharing of electron pairs between two atoms.
The chemical requirement for the formation of a covalent bond is that electrons are shared by a number of atoms. This results in the bonding of the atoms together.
...both electrons in the covalent bond are supplied by the same atom.
a polar covalent bond
by sharing of valence electrons
An ion
In a nonpolar covalent bond the difference between the electronegativities of the two atoms are not significant.
The type of formation for a covalent bond is 2s+3p+2s+4d

merica is sexxxy.
...both electrons in the covalent bond are supplied by the same atom.
covalent bonds can be broken if energy is added to a molecule. this formation of covalent bond is accompanied by energy given off.
a polar covalent bond
by sharing of valence electrons
An ion
In a nonpolar covalent bond the difference between the electronegativities of the two atoms are not significant.
Shared electrons produce a covalent bond.
the condition for covalent bond is that both has to be non metal so that they can share their valence electrons to form duplet or octet configuration
