The trioxide, which is volatile at high temperatures, is the precursor to virtually all other Mo compounds as well as alloys. Molybdenum has several oxidation states, the most stable being +4 and +6 (bolded in the table at left). Molybdenum(VI) oxide is soluble in strong alkaline water, forming molybdates (MoO 4 2−).
All unstable isotopes of molybdenum decay into isotopes of zirconium, niobium, technetium, and ruthenium. [5] Molybdenum-100, with a half-life of 7.07 × 10 18 years, is the only naturally occurring radioisotope. It undergoes double beta decay into ruthenium-100. Molybdenum-98 is the most common isotope, comprising 24.14% of all molybdenum on ...
Molybdenum nitride can be synthesized through various methods, [2] [3] including: Direct nitridation: Molybdenum metal can react with nitrogen gas at elevated temperatures to form Mo 2 N. Ammonolysis : Molybdenum precursors, such as molybdenum oxides or molybdates, can be treated with ammonia gas or ammonia-containing solutions to produce ...

Molybdenum is an essential element in most organisms; a 2008 research paper speculated that a scarcity of molybdenum in the Earth's early oceans may have strongly influenced the evolution of eukaryotic life (which includes all plants and animals). [1] At least 50 molybdenum-containing enzymes have been identified, mostly in bacteria.
