See the answer below.
Work Step by Step
a,b) Outermost shell is 4, fourth period
5 electrons past the noble gas core: group 5
It's Vanadium, V
c) Transition metal, it's in the d-block.
d) 3 unpaired electrons, it's paramagnetic.
e) $(n, \ell, m_\ell, m_s)$ sets from left to right:
(3,2,-2,-1/2),(3,2,-1,-1/2), (3,2,0,-1/2), (4,0,0,-1/2), (4,0,0,+1/2).
f) It loses the two 4s electrons and remains paramagnetic with three unpaired electrons.
