how will we draw a born haber cycle for MgCl2 ?
MgCl2 is formed from Mg and Cl.So we can write the steps for the formation of MgCl2
1)Mg metal exist in solid will convert into gas.
2)Mg(g) will loose 2 electrons to form Mg 2+(this can be written in two steps )
3)Chlorine gas is in form of diatomic molecule will break up into Chlorine atom 2chlorine atoms.
4)Chlorine atom will gain electron to form 2Cl-(g)
5)Mg2+ (g) and Cl-(g) will combine to form MgCl2
here diagram is showing for MgCl you can take a hint for MgCl2
