The formula for calculating the number of electrons in subshells or sub-energy levels is:
Correct answer: C. 2(2l+1)
- A. 2l+1
- B. 2(l+1)
- C. 2(2l+1)
- D. 2(2l-1)
Explanation
Each subshell of qauntum number 'l' contains '2l+ 1' orbitals. According to Pauli's exclusion principle, no more than two electrons can be placed in each orbital. Therefore, the maximum number of electrons is simply twice the number of orbitals that are employed, i.e., 2(2l +1) = 4l +2.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
