The arrangement of sub shells or orbitals is according to _.
Correct answer: C. n+l
- A. 2(l+l)
- B. l+l
- C. n+l
- D. 2(n+l)
Explanation
The n+l rule is used to arrange subshells and orbitals in order of increasing energy where n is the principal quantum number and l is the azimuthal quantum number.

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.
