Question

The
element which shows +1 oxidation state has three shells, find its subshell electronic
configuration? )

Answer 1

Answer:fluorine

Explanation:

this is because it has electronic configuration

1s^2 2s^2 2p^5

Transition metal electronic configuration in +3 oxidation state is [Ar]3d

4

The neutral element  electronic configuration is [Ar]4s

2

3d

5

, Atomic number should be =25. Therefore the element is Manganese(Mn)
