[PAR] [TLE] Oxygen [SEP] Oxygen is a chemical element with symbol O and atomic number 8.  It is a member of the chalcogen group on the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.  By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium.  At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula O2 .  Diatomic oxygen gas constitutes 20.8% of the Earth's atmosphere.  As compounds including oxides, the element makes up almost half of the Earth's crust. [PAR] [TLE] Cyclopentadienyl nickel nitrosyl [SEP] Cyclopentadienyl nickel nitrosyl is a blood-red color liquid.  It was discovered by a team at The International Nickel Company.  The molecular formula is (CH)NiNO.  It can be prepared by treating nickelocene with nitric acid.  It is extremely toxic (T+).
