IONIC BOND OR ELECTROVELENT BOND1) the chemical bond formation between two or more atom as a result of the complete transfer of one or more electron from one atom to another atom,,,,,, 2)Electropositive atom losses electron(G.P. 1A to 3A)3
3)Electronegativity atom gain electron (G.P. 5A to 7A)
4)The electrostatic force of attraction between cation and anion is called an ionic bond,,,,,,,
1)Electronegativity difference is directly proportional to an ionic bond,,,,, means electronegativity difference is high then the ionic bond is high,,,,,,, ex. Becl2 and Mgcl2 which is a more ionic character,,,,,,, Mgcl2 is a more ionic character because of E.N. difference is 1.8 and Becl2 E.N. difference is 1.5FACTOR AFFECTING OF IONIC BOND
CONDITION FOR FORMING IONIC BOND1)formation of an ionic bond depend upon this three-factor1) ionization energy 2) Electron affinity 3)lattice energy PROPERTY OF IONIC COMPOUND 1) ionic compound hard, the crystal in brittle, due to strong electrostatic force of attraction
2) the ionic compound has high boiling and melting point due to strong electrostatic force of attraction 3) high soluble in water
