Fill in the blanks from the choices given below : In covalent compounds, the bond is formed due to the ............ ( "sharing"//"transfer" ) of electrons.

Ionic bond is defined as the electrostatic force of attraction holding the oppositely charged ions. Ionic compounds are mostly crystalline solid having high melting and boiling points, electrical conductivity in moleten state, solubility in water etc. Covalent bond is defined as the force which binds atoms of same or different elements by mutual sharing of electrons in a covalent bond. Covalent compounds are solids, liquids or gases. They have low melting and boiling points compounds. They are more soluble in non-polar solvents. The amount of energy released when one mole of ionic solid is formed by packing of gaseous ion is called :
