The question "What shape is Spdf?" is a bit misleading. S, p, d, and f are notations for different types of atomic orbitals, not a single entity called "Spdf." Each type of orbital has a distinct shape. Therefore, the question should be understood as asking for the shapes of s, p, d, and f orbitals. However, since f orbitals aren't mentioned in the reference, this answer will focus on s, p, and d orbitals.
Here's a breakdown of their shapes based on common chemistry knowledge and the supplied reference:
-
s-orbital: The reference states "An s-orbital has a spherical nucleus in the centre". Therefore, an s-orbital is spherical.
-
p-orbital: The reference states "a p-orbital is dumbbell-shaped". Therefore, a p-orbital is dumbbell-shaped.
-
d-orbital: The reference states "four of the five d orbitals are cloverleaf-shaped. The fifth d orbital is fashioned like a long dumbbell with a doughnut in the centre." Therefore, four d-orbitals are cloverleaf-shaped, and one is a dumbbell with a doughnut.
Therefore, S, P, and D orbitals have distinct shapes:
| Orbital Type | Shape | Description |
|---|---|---|
| s | Spherical | A sphere with the nucleus at its center. |
| p | Dumbbell | Two lobes on either side of the nucleus. |
| d | Cloverleaf/Dumbbell | Four orbitals are cloverleaf-shaped, and one resembles a dumbbell with a ring around it. |
