I think like these elements have d and f shells so no of valence electrons change with ground and excited state.

ok
but the answer given by the other person is pucca right
ok but why didn't you gave reason for my other question that I had asked in comment box

because due to more electron in n- 1 d orbitalwhich is close to energy level
did you mean 2nsquare rule
where n is number of shell
no their are further rules like aufbau rule , pauli exclusion ,hunds rule , why are u worring .
this question is not going to come in ur exam this is 11 class question.
no need to woorry
I just wanna no about transition metal . and I'm not worried about it . it's just my hobby to learn
I mean know
although I'm a student of standard 8 but I love to learn these things like discovery of electrons , protons , neutrons , polyatomic ions ,isotopes etc. I know it's above my class not my interest
aufbau rule states about spdf. am I right
but thanks
