how many atomic orbitals are the in a g subshell?

There are 9 atomic orbitals in a g shell (l = 4, so m = 2l + 1 = 9).

According to Pauli's exclusion principle, an orbital can accommodate a maximum of 2 electrons. Hence, the population of g subshell is 18 electrons.

Atoms consist of three subatomic particles: protons, neutrons, and electrons. A proton has a positive charge and a neutron has no charge. Both protons and neutrons are found in the densely packed, positively charged nucleus.

Electrons within an atom can be assessed according to the shell, subshell, and orbital to which they are assigned. These assessments are based on the quantum mechanical model. Shells are numbered as n=1,2,3,4, etc. and increase in size and energy as they get further away from the nucleus.

Shells can be subdivided into subshells. The maximum number of subshells is equivalent to the shell number. For example, when n=1 (first shell), only one subshell is possible and when n=2 (second shell), two subshells are possible.
