Full Answer

Neutral atoms have the same number of protons and electrons, giving them a net charge of zero. The number of protons in an element corresponds to that element's atomic number, so xenon has 54 protons. For the atom to have a net charge of zero, xenon must also have 54 electrons.

Xenon is used mostly for research purposes, but it is also used to make high-speed flash bulbs for photography equipment. The electron structure of xenon makes it very volatile, which is why the element is useful for producing specialized lighting equipment. Pure xenon is not toxic, but it forms highly toxic compounds when it combines with other elements, according to the Royal Society of Chemistry website.
