Solid state.
Selenium is usually amorphous, brick-red powder.
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.
Oxidation number of Se is +6. Oxidation number of O is -2.
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.
The element, Selenium, is a solid at room temperature.
