One+Electron+Atoms

=One-Electron Atoms=

A one electron atom is characterized as one electron combined with a nucleus. In the simple case, an example would be a hydrogen atom. One proton would be the nucleus and one electron would be paired with the proton. Another example would be a lithium ion. The nucleus would contain three protons and four neutrons (three neutrons if it was an isotope), but only one electron.
