Which of the following is the electronic configuration of sodium11?
Correct answer: B. [Ne]3s1
- A. [He]2s1
- B. [Ne]3s1
- C. [Ne]3s2
- D. [He]2s2
Explanation
Option B is correct since sodium11 has 11 electrons whereas Ne has 10 electrons.The [Ne] part represents the noble gas configuration of neon, and the 3s1 indicates that there is one electron in the 3s orbital.

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.
