Answer:
since the difference between last and second last and ionization enthalpy is very much therefore it can be said that at after 5x ionization enthalpy noble gas electronic configuration must be achieved by the atom therefore the number valence electrons of the atom must be 3 and since in case of halide , atoms used to have their maximum valency therefore compound form must be of type MX3
Explanation:
Say the metal is M and halogen X
The formula is MX3
As halogens have valency -1 and the given metal will have valency +3
because the first,second,and third ionisation enthalpies are increasing gradually but tue difference between third and forth enthalpy is very high which shows the metal achieves noble gas configuration when 3 electrons have been removed from it .
