The periodic table includes all of the known elements in the world. how are elements arranged on the periodic table? a. by the number of neutrons found in the element b. by the element's name c. by their atomic number d. by their atomic mass

C: by their atomic number

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.
