We are asked to determine the maximum number of electrons that can have each of the following designations: 2f, 2dxy, 3p, 5dyz, and 4p.

The m values (for each ℓ) represent electron orbitals for the subshell:

s subshell→ 1 orbital
p subshell→ 3 orbitals
d subshell → 5 orbitals
f subshell 7 orbitals
g subshell → 9 orbitals

Each orbital can have 2 electrons.

2f

• f → 7 orbitals → 14 electrons

2f  can have a maximum number of  14 electrons

2dxy

• d → 5 orbitals → dxy, dxz ,dyz ,dx2y2 ,dz2
• dxy → 1 orbital → 2 electrons

2dxy can have a maximum number of  2 electrons
