d
Verified step by step guidance1
Recall that atomic orbitals are regions in space where there is a high probability of finding an electron, and these orbitals have different shapes depending on the subshell type.
The subshells are labeled as s, p, d, and f, each corresponding to different shapes: s orbitals are spherical, p orbitals are dumbbell-shaped, d orbitals have more complex cloverleaf shapes, and f orbitals are even more complex.
Since the question asks for the subshell letter that corresponds to a spherical orbital, focus on the shape associated with each subshell letter.
Identify that the 's' subshell corresponds to spherical orbitals, meaning the electron density is evenly distributed in all directions around the nucleus.
Therefore, the correct subshell letter for a spherical orbital is 's'.
