 |  Subject: Hydrogen atom  Thu Dec 30, 2010 5:11 pm | |
| A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively-charged proton and a single negatively-charged electron bound to the nucleus by the Coulomb force. The most abundant isotope, hydrogen-1, protium, or light hydrogen, contains no neutrons; other isotopes of hydrogen, such as deuterium, contain one or more neutrons. This article primarily concerns hydrogen-1. The hydrogen atom has special significance in quantum mechanics and quantum field theory as a simple two-body problem physical system which has yielded many simple analytical solutions in closed-form. pubblicità su internetEnglisch Deutsch Übersetzung | |
