# Can principal quantum number and azimuthal quantum number be equal?

## Can principal quantum number and azimuthal quantum number be equal?

Shreya no you can’t have azimuthal quantum number equal to 1,see formula for azimuthal quantum number is n-1 where n is your principal quantum number. for example if your principle quantum number is 2 your azimuthal quantum number will be 0,1.

What is the relationship between the principal quantum number?

The principal quantum number, n, describes the energy of an electron and the most probable distance of the electron from the nucleus. In other words, it refers to the size of the orbital and the energy level an electron is placed in. The number of subshells, or l, describes the shape of the orbital.

What does the azimuthal quantum number determine?

The azimuthal quantum number is a quantum number for an atomic orbital that determines its orbital angular momentum and describes the shape of the orbital.

### What is the azimuthal quantum number and what is its function?

noun Physics. the quantum number that designates the orbital angular momentum of a particular quantum state of an electron in an atom and that assumes integral values from zero to one less than the value of the principal quantum number. Also called orbital quantum number.

What is the formula of azimuthal quantum number?

Azimuthal quantum number (l) = 2. Magnetic quantum number (ml) = – 2 , – 1 , 0 , 1, 2.

Which of the following is significant of azimuthal quantum number?

Azimuthal quantum number is also known as the subsidiary quantum number and is represented by the letter l. It represents the subshell to which the electron belongs. It also defines the shape of the orbital that is occupied by the electron. Its value depends upon the value of principal quantum number ‘n’.

## Why is azimuthal quantum number important?

Azimuthal Quantum Number is a quantum number for atomic orbitals which helps identify their orbital angular momentum. They define the shape of the orbital. Azimuthal quantum number is the second set of quantum numbers, and is very helpful in determining the unique set of an electron’s quantum state.

What is the principle and azimuthal quantum numbers of electrons in 4f orbital?

For a 4f orbital, the principal quantum number is n = 4, the azimuthal quantum number is 3.

What is azimuthal quantum number in physics?

Azimuthal quantum number describes the shape of orbital. It is denoted by . Values of are from zero to n-1. With the help of the value of azimuthal quantum number we can determine the total number of energy sub-levels in a given energy level.

### What is the formula for the principal quantum number?

Atoms and Atomic Arrangements When the principal quantum number n=1, l must be equal to zero, and an electron in this state would be designated by the symbol 1s. Such a state can only have a single value of the inner quantum number m=0 but can have values of or for the spin quantum number s.
