Answer 2

Hello Dear,

◆ Answer - (B)

A maximum number of electrons which can be accommodated in the nth energy level is given by 2n².

● Explaination -

• For nth energy level, no of electrons are 2n².

Example,

1. For 1st energy level, No of electrons = 2×1² = 2
2. For 2nd energy level, No of electrons = 2×2² = 8
3. For 3rd energy level, No of electrons = 2×3² = 18
4. For 4th energy level, No of electrons = 2×4² = 32

Hope that helps you...
