Question

alkaline earth metals do not show variable oxidation states. why ?​

Answer 1

Answer:

Transition metals show variable oxidation state as they have both ns and (n-1)d orbitals. the energy difference of these orbitals is very less hence both take part in bond formation and exhibit variable oxidation state. but (n-1)d orbital is not present in alkaline earth metals.

Answer 2

Answer:

Hey buddy !! here's your answer...

➡️alkaline earth metals have two electrons in their valence orbital, resulting with an oxidation state of +2... they are present in s orbital and also lack d orbital .

✔️transition metals show variable oxidation state as they have both ns and (n-1)d orbitals. the energy difference of these orbitals is very less hence both take part in bond formation and exhibit variable oxidation state.

but (n-1)d orbital is not present in alkaline earth metals .

hope it helps !! ✌️❤️
