Question

What is the number of electrons that can accommodate in K shell in case of Lithium?

• A. 2
• B. 3
• C. 1
• D. 4

Answer 1

The correct option is A 2

The atomic number of lithium (Li) is 3.

The maximum number of electrons that can be accommodated in any given shell is $2n^2$ (n= shell number. So for K, shell number is 1).

Therefore, Number of electrons in K shell = $2\times 1^2=2$
