| The Xenon atom has 5 energy levels. The firdt has 2 electrons, the second 8 electrons, the third 18 electrons, the fourth 18 electrons, and the fifth has 8 electrons. |
| This gas makes up 0.086 parts per million of the atmosphere. About half a tonne a year is produced from liquid air and used for research purposes. It is composed of nine stable isotopes and 20 unstable atoms have been recorded in data so far. |
