Answer:
d - orbital
Explanation:
The d-orbital can modelled by a peanut shape.
A peanut shape closely resembles the shape of a double dumb-bell shape. The double dumb-bell shape is like that of a peanut.
- The s-orbital has a spherical shape.
- p - orbital is dumb-bell shaped
- d - orbital is a double dumbell
- f - orbital has a complex shape.
Therefore, since a peanut is like a double dumb-bell, it clearly models the d-orbital.
