Question
The electrons of the same orbitals can be distinguished by(a) Principal quantum number(b) Azimuthal quantum number(c) Spin quantum number(d) Magnetic quantum
Solution
Electrons in the same orbital can be distinguished by the Spin Quantum Number.
Here's why:
(a) Principal Quantum Number (n): This defines the energy level and size of the orbital. Electrons in the same orbital will have the same principal quantum number.
(b) Azimuthal Quantum Number (l): This defines the shape of the orbital. Electrons in the same orbital will have the same azimuthal quantum number.
(c) Spin Quantum Number (s): This defines the direction of the electron spin. It can be +1/2 or -1/2. Electrons in the same orbital can have different spin quantum numbers, which is why they can be distinguished by this.
(d) Magnetic Quantum Number (m): This defines the orientation of the orbital in space. Electrons in the same orbital will have the same magnetic quantum number.
So, the correct answer is (c) Spin Quantum Number.
