Some compounds and their nature are shown in table complete the table by finding out the electron negativity difference between the constituent elements.

   Compounds Difference in electronegativity of constiuent elements Nature of the compound
 Carbon monoxide (CO) 3.44 - 2. 55 = 0.89 Covalent bond
Sodium chloride (Nacl)  3.16 - 0.98 = 2.23 Ionic bond
 Methane (CH4) 2.55 - 2.20 = 0.35 Covalent bond
 Magnesium chloride (MgCl2) 3.16 - 1.31 Ionic bond
 Sodium oxide (Na2O) 3.44 - 0.93 = 2.51 Ionic bond

Generally, the electronegativity difference of the component elements in a compound is 1.7 or more it shows ionic character. If it is less than 1.7 it shows covalent character
