Maximum number of electrons that can be accomodated in 3s orbital are:
Correct answer: B. 2
- A. 1
- B. 2
- C. 6
- D. 10
Explanation
The maximum number of electrons that can be accommodated in a 3s orbital is 2. This is based on the Pauli's Exclusion Principle, which states that no two electrons in an atom can have the same set of quantum numbers. In the 3s orbital, there are two possible values for the spin quantum number (s): +1/2 and -1/2. Therefore, the 3s orbital can hold a maximum of 2 electrons (one pair), each with opposite spins, one with +1/2 and the other with -1/2.

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.
