Can someone explain this
An electron described by the quantum number ,n=4,l=3 can be located in what orbital
A..4f
B..3s
C..3d
D..4p
To determine the orbital in which an electron described by the quantum numbers n = 4 and l = 3 can be located, first, let's understand what each quantum number represents.
The principal quantum number, denoted by "n," represents the energy level or shell in which the electron is located. A higher value of "n" indicates a higher energy level.
The azimuthal quantum number, denoted by "l," is related to the shape of the orbital. It specifies the subshell within a particular energy level. The values of "l" range from 0 to (n-1).
In this case, n = 4 and l = 3. Since the value of "n" is 4, it indicates that the electron is in the fourth energy level or shell. Since the value of "l" is 3, it indicates that the electron is in the "d" subshell.
Using the following notation, the orbital in which the electron can be located is represented by the combination of the principal (n) and azimuthal (l) quantum numbers.
A. 4f: This represents the "f" subshell, which corresponds to l = 3. The orbital cannot be 4f since the principal quantum number n = 4 does not match.
B. 3s: This represents the "s" subshell, which corresponds to l = 0. The orbital cannot be 3s since the azimuthal quantum number l = 3 does not match.
C. 3d: This represents the "d" subshell with l = 2. However, the question states that l = 3, so the orbital cannot be 3d.
D. 4p: This represents the "p" subshell, which corresponds to l = 1. In this case, the principal quantum number n = 4 matches, and the azimuthal quantum number l = 3 also matches. Therefore, the electron described by the quantum numbers n = 4 and l = 3 can be located in the 4p orbital.
So, the correct answer is D - 4p.
