Recall that the angular momentum quantum number \( l \) defines the subshell type: \( l = 0 \) is s, \( l = 1 \) is p, \( l = 2 \) is d, and so on.
The number of orbitals in a subshell is given by the formula \( 2l + 1 \), where \( l \) is the angular momentum quantum number.
Substitute \( l = 2 \) into the formula: \( 2(2) + 1 \).
Calculate the expression to find the number of orbitals in the subshell.
Interpret the result as the total number of orbitals present when \( l = 2 \).
