Nitride. In chemistry, a nitride is a chemical compound of nitrogen. Nitrides can be inorganic or organic, ionic or covalent. The nitride anion, N 3- ion, is very elusive but compounds of nitride are numerous, although rarely naturally occurring.
Lithium nitride is prepared by direct reaction of elemental lithium with nitrogen gas: [2] 6 Li + N 2 → 2 Li 3 N. Instead of burning lithium metal in an atmosphere of nitrogen, a solution of lithium in liquid sodium metal can be treated with N 2. Lithium nitride must be protected from moisture as it reacts violently with water to produce ammonia:
Silicon nitride is a chemical compound of the elements silicon and nitrogen. Si 3 N 4 (Trisilicon tetranitride) is the most thermodynamically stable and commercially important of the silicon nitrides, [6] and the term ″Silicon nitride″ commonly refers to this specific composition.
Nitrogen compounds. The chemical element nitrogen is one of the most abundant elements in the universe and can form many compounds. It can take several oxidation states; but the most common oxidation states are -3 and +3. Nitrogen can form nitride and nitrate ions. It also forms a part of nitric acid and nitrate salts.
Chemistry. Magnesium nitride reacts with water to produce magnesium hydroxide and ammonia gas, as do many metal nitrides. In fact, when magnesium is burned in air, some magnesium nitride is formed in addition to the principal product, magnesium oxide. Thermal decomposition of magnesium nitride gives magnesium and nitrogen gas (at 700-1500 °C).
An ion (/ ˈaɪ.ɒn, - ən /) [1] is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention. The net charge of an ion is not zero because its total number of electrons ...
Sodium nitride is the inorganic compound with the chemical formula Na 3 N. In contrast to lithium nitride and some other nitrides , sodium nitride is an extremely unstable alkali metal nitride . It can be generated by combining atomic beams of sodium and nitrogen deposited onto a low-temperature sapphire substrate. [ 1 ]
The most stable crystalline form is the hexagonal one, also called h-BN, α-BN, g-BN, and graphitic boron nitride. Hexagonal boron nitride (point group = D 3h; space group = P6 3 /mmc) has a layered structure similar to graphite. Within each layer, boron and nitrogen atoms are bound by strong covalent bonds, whereas the layers are held together ...
