Identify each element below, and select all the symbols of the other elements in its group.
(a) [Ar] 4s23d2

    Sc
    Mo
    Hg
    Rf
    Zr
    Cu

(b) [Ne] 3s23p3

    N
    Be
    Si
    Cl
    Ge
    Bi

(c) [Ar] 4s23d7

    V
    Cr
    Hf
    Rh
    Ir
    Hg
As there seems to have been some confusion, I should probably make it clear that the list of elements only applies to the second part of the question, where I need to identify which of the elements listed are in the same group.

I don't understand the second part of the question, but (a) is titanium (Ti), (b) is phosphorous (P), and (c) is cobalt (Co).

For a,  should be Titanium, Ti... For the second part of the question is Cu - just go through the group and the elements give to find the elements.  

For b, should be P, and the elements in the group are Si, Cl,

For c, should be Colbat and the elements are V, Cr.
