Two electrons present in M shell will differ ina)Principal quantum num...
Explanation:
When two electrons are present in the same M shell, they will differ in terms of their spin quantum number.
Principal Quantum Number (n):
The principal quantum number determines the energy level or shell in which an electron is present. It determines the distance of the electron from the nucleus. In this case, both electrons are present in the same M shell, so the principal quantum number will be the same for both electrons.
Azimuthal Quantum Number (l):
The azimuthal quantum number determines the shape or subshell of the electron's orbital. It can have values ranging from 0 to (n-1). In this case, since both electrons are present in the same M shell, they will have the same azimuthal quantum number.
Magnetic Quantum Number (m):
The magnetic quantum number determines the orientation of the electron's orbital in space. It can have values ranging from -l to +l. In this case, since both electrons are present in the same M shell, they will have the same magnetic quantum number.
Spin Quantum Number (s):
The spin quantum number determines the direction of the electron's spin. It can have two possible values: +1/2 (spin-up) or -1/2 (spin-down). In this case, the two electrons in the M shell will differ in terms of their spin quantum number. One electron will have a spin-up orientation (+1/2) and the other electron will have a spin-down orientation (-1/2).
Therefore, the correct answer is option D) Spin quantum number. The two electrons in the M shell will differ in terms of their spin quantum number.
When two electrons are present in the same M shell, they will differ in terms of their spin quantum number.
Principal Quantum Number (n):
The principal quantum number determines the energy level or shell in which an electron is present. It determines the distance of the electron from the nucleus. In this case, both electrons are present in the same M shell, so the principal quantum number will be the same for both electrons.
Azimuthal Quantum Number (l):
The azimuthal quantum number determines the shape or subshell of the electron's orbital. It can have values ranging from 0 to (n-1). In this case, since both electrons are present in the same M shell, they will have the same azimuthal quantum number.
Magnetic Quantum Number (m):
The magnetic quantum number determines the orientation of the electron's orbital in space. It can have values ranging from -l to +l. In this case, since both electrons are present in the same M shell, they will have the same magnetic quantum number.
Spin Quantum Number (s):
The spin quantum number determines the direction of the electron's spin. It can have two possible values: +1/2 (spin-up) or -1/2 (spin-down). In this case, the two electrons in the M shell will differ in terms of their spin quantum number. One electron will have a spin-up orientation (+1/2) and the other electron will have a spin-down orientation (-1/2).
Therefore, the correct answer is option D) Spin quantum number. The two electrons in the M shell will differ in terms of their spin quantum number.
