Give the notation for the valence-shell configuration (including the outermost d-electrons) of (a) the alkali metals; (b) Group 15 elements; (c) group 5 transition metals; (d) the "coinage" metals (Cu, Ag, Au).
Thanks!

Re: 1E.25
Alkali — (no d electrons) s1
Grp 15 — if period 3+: (n-1)d10ns2np3
Grp 5 — (n-1)d3ns2
Coinage metals — acheive greater stability with a partially or completely filled d subshell
(n-1)d5ns1 OR (n-1)d10ns1
n = principal quantum number
