Hiya
So the definition of a transition metal is a partially filled d orbital, but Im confused as to whether its partially filled when its an ion?
ok that's my first question
and also I dont underdstand why scandium isnt a transition metal , electron configuration Sc: [Ar] 4s2, 3d1,
i checked the net, and it said that scandium looses 3 e- and therefore has no e- in its d shells, but why is it that it looses 3 electrons, why couldnt it loose 2 of its 4s electrons?
because Zinc is also not a transition metal because it has a full d orbital, but thats not even when its an ion?
Thank you very much for all help !!
