The elemental selenium in selenium dioxide monohydrate exists as Se(IV) in the +4 oxidation state. It is bonded to two oxygen atoms in a linear configuration. The oxygen atoms are bound to the selenium atom in a double bond.
Selenium is a solid at room temperature and pressure, making it a solid state of matter.
The most common oxidation state for selenium is -2, but it can also exist in oxidation states of +4 and +6 depending on the compound it is in.
Excited state selenium refers to selenium atoms or ions that have absorbed energy, causing their electrons to move to higher energy levels. This temporary configuration is unstable, and the electrons will eventually return to their original energy levels, releasing the absorbed energy as light. This process is the basis for selenium's use in photovoltaic cells and other light-sensitive technologies.
Selenium is a solid at room temperature. It is a nonmetal in the oxygen group, and its melting point is 221 degrees Celsius.
