1.23 What exponential notation do the following abbreviations represent: (a) d, (b) s (c) f, (d) , (e) M, (f) k, (g) n, (h) m, (i) p?​

(a) 1x10^-1 (b) 1x10^-2 (c) n/a (d) 1x10^-6 (e) 1x10^6 (f) 1x10^3 (g) 1x10^-9 (h) 1x10^-3 (i) n/a

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.
