Question

What quantum numbers specify these subshells?
1s ,5p ,6d
n ,n ,n

Answer 1

The subshells are as follows:

     1s, 5p and 6d

Principal quantum number (n): This quantum number indicates the number of the subshells. It can have the integer values.

Therefore, the principal quantum numbers for the above subshells are shown below:

                     1s: n = 1

                     5p: n = 5                

                     6d: n = 6

Angular momentum quantum number (l): This quantum number tells about the shape of the orbitals. The value of l is generally designated by the letters s, p, and d%u2026.as follows:

              s = 0, p = 1, d = 2

Therefore, the angular momentum quantum numbers for the above subshells are shown below:

                    1s: l = 0

                     5p: l = 1                

                     6d: l = 2

Magnetic quantum number (m_l): This quantum number describes the orientation of the orbital in space. For a certain value of l, there are (2l+1) integral values of m_l as follows:

                           -l, (-l+1) %u2026.0, %u2026. (+l-1), +l

Therefore, the angular momentum quantum numbers for the above subshells are shown below:

                     1s: m_l = 0

                     5p: m_l = -1, 0, +1                

                     6d: m_l = -2,-1, 0, +1, +2

Spin quantum number (m_s): This quantum number indicates the spin of the electrons in the orbital. The electrons are not given to the subshells. Therefore, no spin quantum number for the subshells.

Therefore, the first three quantum numbers specifies these subshells.
