# What are the quantum numbers for SE?

## What are the quantum numbers for SE?

Selenium atoms have 34 electrons and the electronic shell structure is [2, 8, 18, 6] with Atomic Term Symbol (Quantum Numbers) 3P2.

What is azimuthal quantum number example?

The azimuthal (or orbital angular momentum) quantum number describes the shape of a given orbital. For example, if n =3, the azimuthal quantum number can take on the following values – 0,1, and 2. When l=0, the resulting subshell is an ‘s’ subshell.

What is the value of azimuthal quantum number for S Subshell?

No. of electrons

Azimuthal quantum number, l Subshell Shape
0 s spherical
1 p dumbbell
2 d dumbbell and doughnut
3 f

### When the azimuthal quantum number has the value of 2?

When the azimuthal quantum number has the value 2, the number of orbitals possible is. Each subshell of quantum number l contains 2l+1 orbitals. Thus, if l=2, then there are (2×2)+1=5 orbitals.

What is azimuthal quantum number with symbol?

It is also known as the orbital angular momentum quantum number, orbital quantum number or second quantum number, and is symbolized as ℓ (pronounced ell).

What is the orbital configuration of SE?

The ground state electron configuration of ground state gaseous neutral selenium is [Ar]. 3d10. 4s2. 4p4 and the term symbol is 3P2.

#### What kind of quantum number is azimuthal orbital?

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. The azimuthal quantum number is the second of a set of quantum numbers which describe the unique quantum state of an electron…

Which is the second quantum number for an electron?

The azimuthal quantum number is the second of a set of quantum numbers that describe the unique quantum state of an electron (the others being the principal quantum number, the magnetic quantum number, and the spin quantum number ).

What is the value of the spin quantum number?

The range of Azimuthal Quantum number is between 0 to n-1. What is the value of the spin quantum number? The value of spin quantum number is 2. For a quantum number, if n=4, what is the value that is not equal to l?

## Which is the best description of a quantum number?

Also known as orbital/angular momentum quantum number, it refers to the subshell to which an electron belongs. The value of ‘ℓ’ tells the specific subshell; s, p, d and f each having a unique shape. It also designates the shape of the given orbital. The value of ‘ℓ’ tells the total number of angular nodes in an orbital.
