In a plot of probability of finding the electron in the hydrogen ground state versus the distance from the nucleus, the maximum
Lunna [17]

In a plot of the probability of finding the electron in the hydrogen ground state versus the distance from the nucleus, the maximum occurs (A) at a0. the first Bohr radius.

<h3>What is an electron?</h3>
  • The electron is a subatomic particle with a negative one elementary charge electric charge.
  • Electrons are the first generation of the lepton particle family and are widely regarded as elementary particles due to the lack of known components or substructure.

Electron in the hydrogen:

  • Hydrogen has the simplest electron configuration to write because it just contains one electron.
  • There is essentially only one electron surrounding the Hydrogen nucleus.
  • Because hydrogen only has one electron, its configuration is 1s1.
  • The maximum occurs at a0, the first Bohr radius, in a plot showing the chance of finding the electron in the hydrogen ground state vs the distance from the nucleus.

Therefore, in a plot of the probability of finding the electron in the hydrogen ground state versus the distance from the nucleus, the maximum occurs (A) at a0. the first Bohr radius.
