The second ionization enthalpy of calcium is more than that the first and yet calcium forms CaCl_(2) and not CaCl. Why ?

The second ionization enthalpy of calcium is more than that the first

1.	The second ionization enthalpy of calcium is more than that the first and yet calcium forms CaCl_(2) and not CaCl. Why ?
Answer» SOLUTION :The higher ENTHALPY of lattice FORMATION of `Ca^(2+)` IONS more than COMPENSATES the higher second ionization enthalpy of calcium .
