science physics# What are the possible values of the angular momentum quantum number L?

Last Updated: 10th April, 2020

**Angular Momentum quantum number**(

**l**)describes the shape of the orbital. The

**allowed values**of

**l**range from 0 to n - 1. The magnetic

**quantum number**(ml) describes the orientation of the orbital inspace.

Likewise, people ask, what does the angular momentum quantum number determine?

The **angular momentum quantum number**, ℓ, isthe **quantum number** associated with the **angularmomentum** of an atomic electron. The **angular momentum quantumnumber determines** the shape of the electron'sorbital.

what does the quantum number specify? The principal **quantum number** defines the generalsize and energy of the orbital. The l value **specifies** theshape of the orbital. Orbitals with the same value of l form asubshell. In addition, the greater the angular momentum **quantumnumber**, the greater **is** the angular momentum of anelectron at this orbital.

Also to know is, what are the possible values of L?

The number of **values** of the orbital angularnumber **l** can also be used to identify the number ofsubshells in a principal electron shell: When n = 1, **l**= 0(**l** takes on one value and thus there can only be onesubshell) When n = 2, **l**= 0, 1 (**l** takes on two**values** and thus there are two **possible**subshells)

What is the formula of azimuthal quantum number?

The angular momentum **quantum number**, l, (alsoreferred to as the secondary **quantum number** or **azimuthalquantum number**) describes the shape of the orbital that anelectron occupies. The lowest possible value of l is 0, and itshighest possible value, depending on the principal **quantumnumber**, is n - 1.
