The following combination for quantum numbers n=4; l=3; ml=-1 is allowed.
Is the following combination, n=4; l=3; ml=-1 allowed or not? If not, suggest two ways to correct them.
The quantum number is used to define the location of electrons, and an orbital is a place inside the atom where an electron can be found. The quantum number of the shell orbitals of an atom depends on the number of electron shells it contains.
The quantum number sets that can be utilized to characterize an electron are as follows:
Principal quantum number (n)
Orbital quantum number (l)
Magnetic quantum number (m)
Spin quantum number (s)
From 1 to infinity, the primary quantum number can take on positive integer values i.e. n ≤ 1
The range of positive integer values for an orbital quantum number is 0 to (n - 1) i.e. l ≤ n-1
The range of a magnetic quantum number, m is from -l to +l
The only possible value for a spin quantum number is ±1/2.
For n = 4
l becomes, 4 -1 or 4 - 2 or 4 - 3 or 4 - 4 = 3, 2, 1, 0
For l = 3, ml becomes = -3, -2, -1, 0, +1, +2, +3
Therefore, the combination n=4 ; l=3 ; ml=-1 is correct.
