The electron density between the s and 2s orbitals is

Correct answer: B. zero

  • A. high
  • B. zero
  • C. low
  • D. negligible

Explanation

The electron density between the s and 2s orbitals is zero. In an atom, electrons occupy specific energy levels and orbitals. The s orbital is a spherical-shaped orbital that represents the region of highest electron density around the nucleus. The 2s orbital is a higher energy orbital compared to the s orbital, but it also has a spherical shape. Between these two orbitals, there is no region of electron density. The s orbital and 2s orbital are separated by a node, which is a region of zero electron probability. The electron density is highest within the s orbital and gradually decreases towards the node. Beyond the node, the electron density starts to increase again within the 2s orbital. Therefore, between the s and 2s orbitals, there is a region of zero electron density.

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.
