An element has the following subatomic particles: 8 protons, 8 neutrons, 8 electrons. What element is it?

Oxygen is the answer. it has 8 neutrons and 8 electrons as well as 8 protons.

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.
