No, selenium is solid.

Hydrogen selenide, with formula H2Se, is formed from reacting hydrogen and selenium.
Xenon as it is a noble gas. Noble gases are inert and do not react with anything. Selenium is a solid Chlorine is a green coloured highly reactive poisonous gas. Carbon is a non-metallic solid.
Selenium should gain two electrons and lose six electrons to achieve a noble gas electron configuration.
None. The Se2- ion is isoelectronic with Krypton.
It doesn't seem likely. Selenium isn't terribly reactive, and selenium monochloride exists in equilibrium with a different kind of selenium chloride, chlorine gas, and elemental selenium; this indicates that there's not a huge energy difference between the uncombined elements and the compound, as you would expect there to be if they "blew up" when combined.
The noble gas configuration for selenium is [Ar] 3d10 4s2 4p4, which means it has the same electron configuration as argon, followed by 4d10 4p4 electrons.
at normal temperature and pressure it is a solid. Try this link http://en.wikipedia.org/wiki/Selenium ***Seeing as I take a Selenium tablet everyday, I'd too say it is a solid.
This compound is called selenium hexafluoride.
