Using the periodic table, determine which material is most likely to be a good conductor.
a. sodium
b. bromine
c. carbon
d. oxygen

Sodium is the answer

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.
