When the subsidiary quantum numbers (l) equals 1, the shape of the orbital is
Answer Details
The subsidiary quantum number, often referred to as the azimuthal quantum number or angular momentum quantum number, is denoted by l. This quantum number defines the shape of the atomic orbital. The value of l determines the type of orbital as follows:
l = 0: This corresponds to an s orbital, which has a spherical shape.
l = 1: This describes a p orbital, which has a dumb-bell shape.
l = 2: This corresponds to a d orbital, which has a more complex shape, often described as a cloverleaf.
l = 3: This describes an f orbital, which has an even more complex structure.
For l = 1, the atomic orbital is a p orbital, which is characterized by its dumb-bell shape. This means that the electron density is concentrated in two lobes on opposite sides of the nucleus, resembling a dumb-bell.
