Covalent bonding is the sharing of electrons between atoms. The atoms form bonds to stabilize themselves and a number of factors determine the nature and characteristics of the bond formed. If the difference in the electronegativity of the bonding atoms is between 0.4 to 1.6, the bond forms is a polar covalent bond, while if the electronegativity difference is below 0.4, the bond is a non-polar covalent bond. To write a formula that stands for the exact compound you have in mind, you often must write the structural formula instead of the molecular formula.
