Two electrons present in same orbital can be distinguished by:
Correct answer: C. Spin quantum number
- A. Principal quantum number
- B. Azimuthal quantum number
- C. Spin quantum number
- D. Magnetic quantum number
Explanation
Option C is correct.Two electrons present in the same orbital can be distinguished by their spin quantum number. The spin quantum number can have two values, +1/2 and -1/2. This means that there are two possible ways for two electrons to occupy the same orbital, with opposite spins.The principal quantum number, azimuthal quantum number, and magnetic quantum number all describe the spatial distribution of an electron in an atom. They do not tell us anything about the spin of the electron. Therefore, the answer is spin quantum number.The principal quantum number, azimuthal quantum number, and magnetic quantum number all describe the spatial distribution of an electron in an atom. They do not tell us anything about the spin of the electron. Therefore, the answer is spin quantum number

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
