Expert Answer:

n=4 , Whih means element belongs to 4th period. d-orbitals are incompletely filled so it is a d block element.
Number of electrons in outermost d orbital=2
electronic configuration-3d2 4s2
So, Number of s block groups(2)+Number of d block groups(2)-=4
So, this element belongs to 4th group and 4th period.
4th  period is second transition series in d block.
So it belongs to 4th  group and second transition series.
