Question

The orbit closest to the nucleus is called L-shell.

• A. True
• B. False

Answer 1

The correct option is B False

• According to Bohr’s Atomic model electrons revolve around the nucleus in a specific circular path known as orbit or called a shell.
• These shells are called energy levels. It is numbered as 1,2,3,4 and so on, or K, L, M, N…. from the nucleus outwards.
• The first shell is K, the second is L, the third is M, and so on.
• Hence, the first shell is closest to the nucleus which is K, therefore, the given statement is false.
