Verified step by step guidance1
Recall that the number of orbitals in a given subshell is determined by the azimuthal quantum number \( l \). For d orbitals, \( l = 2 \).
The number of orbitals for a given \( l \) is given by the formula \( 2l + 1 \).
Substitute \( l = 2 \) into the formula: \( 2(2) + 1 = 5 \).
This means there are 5 orbitals in any d subshell, including the 5d subshell.
Therefore, the 5d subshell contains 5 orbitals.
