Question

Find the formula of halide of a metal whose successive ionisation enthalpies are x, 2x, 5x, 100x KJ/mol

Answer 1

ionization enthalpy is the amount of energy required to remove an electron from the outer most orbit of an isolated gases atom .

so, above explanation ,
when ionization enthalpy = x kj/mol
then , one electron remove from helogens so, X^+¹ halide

again IE = 2x
then , X+² halide

again IE = 5x
then, X+³ halide

again IE = 100x
then, X+⁴ halide
