Problem 1E.25

Postby Jessica Tejero 3L » Sun Oct 20, 2019 7:16 pm

Hi can someone assist me on this

1E.25 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).

a) ns^1
b) ns^2 np^3
c) omit
d) (n-1)d^10 ns^1

Hi, can you explain the answer to part d) about the coinage metals being (n-1)d^10 ns^1

Is there any specific reason these are exceptions to the pattern of ground state configurations?
