For the quantum number, n and l values for the following sublevel, 4s is n = 4 and l = 0 and the number of orbitals, m is 0.
What are the n and l values for the 4s sublevel?
The position of an electron in an associated atom is described using a set of precise integers known as quantum numbers. Atomic orbitals and the electrons within them are described by quantum numbers. In order to describe its state, an electron in an atom or ion has four quantum numbers.
An electron in an atom can be completely described by four quantum numbers:
Principal quantum number (n)
Azimuthal quantum number (ℓ)
Magnetic quantum number (mℓ)
Spin quantum number (ms)
The electron shell, or energy level, of an electron, is described by its primary quantum number. The value of n spans from 1 to the atom's outermost electron or the shell, thus
n = 1, 2, ...
The subshell is described by the azimuthal quantum number, also referred to as the (angular momentum quantum number or orbital quantum number), and by the relation, it provides the magnitude of the orbital angular momentum.
ℓ = 0, 1, 2,..., n − 1
The orbital angular momentum is projected along a given axis according to the magnetic quantum number, which describes the particular orbital (or "cloud") within that subshell:
m from -1 to +1
The spin quantum number gives the projection of the spin angular momentum S along the designated axis and describes the intrinsic spin angular momentum of the electron within each orbital.
s = ±1/2
In the following sublevel, 4 is the principal quantum number i.e n = 4
s is the subshell that specifies the azimuthal quantum number.
For s, l = 0
If l = 0 then ml = 0
Therefore, n, l and m values of the 4s sublevel become 3, 0 and 0 respectively.
