| In the course of the 20th century, science successively named electrons, protons, neutrons, and quarks. |
| Surrounding it is a cloud of electrons, which are small, light subatomic particles with a negative charge. |
| As they moved closer to the nucleus, the electrons would begin emitting their quanta of energy as light. |
| He began to tell me about whirling electrons and orthicon-tubes and other nonsense, but I cut him short with an abrupt wave. |
| Bohr realized that the idea of a quantum of energy could explain how the electrons in the atom are arranged. |
| It describes a world in which electrons, quarks and the like are point particles that move in a manner dictated by the wavefunction. |
