The maximum number of electrons that can be accommodated in the outermost orbit is-

Correct option is A

The correct answer is (a) 8.
· The maximum number of electrons that can be accommodated in the outermost orbit (also known as the valence shell) of an atom is 8. This is based on the octet rule, which states that atoms tend to have eight electrons in their valence shell to achieve stability, similar to the configuration of noble gases.
Information Booster:
· Electron Configuration: The general formula for the maximum number of electrons in a shell is given by 2n2, where n is the shell number.
· For Example: In the third shell (n = 3), the maximum number of electrons is 2×32=182 \times 3^2 = 182×32=18. However, the outermost shell cannot have more than 8 electrons, as per the octet rule.
