Question

How many unpaired electrons are there in Bk Y and V

Answer 1

Explanation:

For V it will be [1][1][1][0][0], or three unpaired electrons. When transition metals lose electrons, they lose the 4s electrons BEFORE the 3d ones, so Ti(2+) will be (1s)2(2s)2(2p)6(3s)2(3p)6(4s)0(3d)2 and it will still have two unpaired electrons.
