Which one of the following has the same number of electrons as an alpha particle?

Correct answer: B. H+

  • A. H
  • B. H+
  • C. H2
  • D. He

Explanation

Hydrogen ion (H+). It contains the same number of electrons as an alpha particle, i.e. 0 electrons. It's worth noting that alpha particles contain the same number of protons as Helium , i.e. 2 protons. There are no electrons in both H+ and alpha particle.

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.
