If the consecutive ionization energies of an element A are 496, 4564, 6918, 9542 kJ/mole respectively, the formula of the oxide formed by A is:
An element X is having the first ionisation enthalpy as 496kJ/mol. It is having second ionisation enthalpy as 4564kJ/mol. While it is having third ionisation enthalpy as 6918kJ/mol. And accordingly the fourth ionisation enthalpy is 9542kJ/mol. Find the formula of the sulphate and chloride of the element.
Plz explain with the reason
One mole of magnesium in the vapour state absorbed 1200 kJ mole−1 of energy. If the first and second ionization energies of Mg are 750 and 1450 kJ mole−1 respectively, the final composition of the mixture is
