The electronic configuration of manganese is:

1s22s22p63d54s2.

a)What is the maximum oxidation state of manganese?

b)Explain how the electronic configuration shows that Mn is a transition element

1 answer

Removing 4s2 gives Mn^2+. Removing 4s2 and 3d5 gives Mn^7+.

3d electrons make the transition in row 3 from Ca to Ga.
