Answer 1

Answer:

When a covalent bond forms with one pair of shared electrons, we call it a single covalent bond. When two pairs are shared, as when two oxygen atoms come together to make a molecule of oxygen, we call it a double covalent bond. Three pairs shared, as in a molecule of nitrogen, is called a triple covalent bond

Answer 2

Answer:

It depends on an elements valence electrons and the number of electrons shared by the compound.

Single bond - sharing of 1 electron between elements. Example: H2, Cl2, H2O

Double bond - sharing of 2 electrons between elements. Example: O2, CO2

Triple bond - sharing of 3 electrons between elements. Example: N2
