Selvin

Selvin is a chemical element with the symbol Sv and atomic number 120. Prior to its discovery, it was referred to as unbinilium. It is the seventh element in group 2 of the periodic table, also known as the alkaline earth metals. Pure selvin is a green-grey colour (about #86A66F on the hex scale), and readily reacts with oxygen on exposure to air, forming a dark green surface layer of selvin nitride (Sv3N2).
