| Nonmetals with eight valence electrons are chemically unreactive. |
| Some materials commonly used as unreactive anodes are platinum and graphite. |
| Once the active fluorine is chemically bound the resulting molecule is generally stable and unreactive. |
| Cooling molten silica below the melting point results in fused silica, a rigid, transparent substance, chemically unreactive to the vast majority of substances. |
| Some unreactive metals react only very slowly, such as copper and lead. |
| The most dense gas known, radon is colorless and chemically unreactive. |
