The successive ionisation enthalpies of an element M are 5.98, 18.82,

1.	The successive ionisation enthalpies of an element M are 5.98, 18.82, 28.44, 119.96, 153.77, ...... e V atom What is the formula of chloride of M?
Answer» Solution :Observing the `I_1, I_2, I_3, I_4, I_5`, .... it is NOTICED that there is a sudden jump from `I_3` and `I_4` This observation gives the idea that the element has 3 ELECTRONS in the OUTER most shell. `M^(3+)` state is STABLE and valency is 3. Formula of CHLORIDE of `M`is `MCI_3`
