The order of size of 's' orbital is as follows?

Correct answer: B. 4s>3s> 2s> 1s

  • A. 4s<3s<2s3s>2s>ls
  • B. 4s>3s> 2s> 1s
  • C. Constant
  • D. None of these

Explanation

The s subshell has 1 orbital that can hold up to 2 electrons, the p subshell has 3 orbitals that can hold up to 6 electrons, the d subshell has 5 orbitals that hold up to 10 electrons, and the f subshell has 7 orbitals with 14 electrons.

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.
