Sharing two pairs makes a double bond. Sharing three pairs makes a triple bond.
The bond formed by the sharing of electrons is called a covalent bond.
That would be covalent bonding. Ionic bonding is the transfer of electrons, covalent is sharing.
An ionic bond
covalent bond
A covalent bond is formed by sharing electrons between atoms. This type of bond occurs between nonmetal atoms.
In a triple bond, one sigma bond is formed from the direct overlap of two atomic orbitals, while the other two pi bonds are formed by the sideways overlap of p-orbitals. So, in total, there are one sigma bond and two pi bonds in a triple bond.
Covalent. In compounds this may be a single or double bond. In the elemental form N2 there is a triple bond.
single bond
A covalent bond is formed as a result of sharing electron pairs.
sharing of electrons
