Question

If element has ionisation enthalpy equal to x, 5x, and 1000x kilo joule per mole if this element combines with halogen explain the formula of the compound is

Answer 1

Answer: If the element is M and halogen is X then compound will be MX2.

this is because there is a steeper increase in the value of third ionization enthalpy which shows that the element is divalent.
