No, selenium is solid.

No, it is a 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.
The noble gas configuration for selenium (Se), which has an atomic number of 34, is [Ar] 3d¹⁰ 4s² 4p⁴. This indicates that selenium has the electron configuration of argon (Ar) plus an additional ten electrons in the 3d subshell, two in the 4s subshell, and four in the 4p subshell.
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.
