noble gas compounds are chemical compounds that include an element from the noble gases, group 18 of the periodic table. although the noble gases are generally unreactive elements, many such compounds have been observed, particularly involving the element xenon. from the standpoint of chemistry, the noble gases may be divided into two groups: the relatively reactive krypton (ionisation energy 14.0 ev), xenon (12.1 ev), and radon (10.7 ev) on one side, and the very unreactive argon (15.8 ev), neon (21.6 ev), and helium (24.6 ev) on the other. consistent with this classification, kr, xe, and rn form compounds that can be isolated in bulk at or near standard temperature and pressure (at least in principle for the highly radioactive radon), whereas he, ne, ar have been observed to form true chemical bonds using spectroscopic techniques, but only when frozen into a noble gas matrix at temperatures of 40 k or lower, in supersonic jets of noble gas, or under extremely high pressures with metals.

while h is not very reactive under standard conditions, it does form compounds with most elements. hydrogen can form compounds with elements that are more electronegative, such as halogens (e.g., f, cl, br, i), or oxygen; in these compounds hydrogen takes on a partial positive charge. when bonded to a more electronegative element, particularly fluorine, oxygen, or nitrogen, hydrogen can participate in a form of medium-strength noncovalent bonding with another electronegative element with a lone pair, a phenomenon called hydrogen bonding that is critical to the stability of many biological molecules. hydrogen also forms compounds with less electronegative elements, such as metals and metalloids, where it takes on a partial negative charge. these compounds are often known as hydrides.
