Question

Which of the following shell can accommodate maximum of 18 electrons ?Required to answer. Single choice.

(1 Point)

2nd shell - M shell

2nd shell - L shell

3rd shell - L shell

3rd shell - M shell

Answer 1

Answer:

Explanation:

Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.[1] For an explanation of why electrons exist in these shells see electron configuration.[2]

Answer 2

Answer:

L shell refers to the principal quantum no., n=2 There are 4 orbital associated with n=2 ⇒ 2x,2px,2py, and 2pzEach orbitals can occupy 2 electrons. Hence the maximum no. of electron a L-shell can occupy is 8.
