It is analogous to the <a href="/facts/Dioxygen/UVNYnKUQ">dioxygen</a> molecule but rarely occurs at room temperature. This violet gas is the dominant species in hot sulfur vapors. S2 is one of the minor components of the atmosphere of <a href="/facts/Io_(moon)/p3Uc8FmK">Io</a>, which is predominantly composed of <a href="/facts/Sulfur_dioxide/jDK1fIDs">SO2</a>. The instability of S2 is usually described in the context of the <a href="/facts/Double_bond_rule/kxtnRvH8">double bond rule</a>. </p>
