Question

Which energy shell is nearest to the nucleus?

Answer 1

Shell:

• According to Bohr’s Atomic model electrons revolve around the nucleus in a specific circular path known as orbit or called a shell.
• Shells have stationary energy levels, the energy of each shell is constant.
• The greater the distance of the orbit from the nucleus, the more shall be the energy associated with it.

K - shell is the nearest shell to the nucleus having the least energy and can occupy maximum 2 electrons.
