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.
Silicon nitride is a chemical compound of the elements silicon and nitrogen. Si. 3N. 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.
Calcium nitride is formed along with the oxide, CaO, when calcium burns in air. It can be produced by direct reaction of the elements: [3] 3 Ca + N 2 → Ca 3 N 2. It reacts with water or even the moisture in air to give ammonia and calcium hydroxide: [4] Ca 3 N 2 + 6 H 2 O → 3 Ca (OH) 2 + 2 NH 3. Like sodium oxide, calcium nitride absorbs ...
This page shows the electron configurations of the neutral gaseous atoms in their ground states. For each atom the subshells are given first in concise form, then with all subshells written out, followed by the number of electrons per shell. For phosphorus (element 15) as an example, the concise form is [Ne] 3s 2 3p 3.
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).
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 ]
Hydrogen doping increases conductivity, whilst doping with metal ions (Al, Cu, Mg) reduces it. [5] [6] The activation energy for lithium transfer across lithium nitride crystals (intercrystalline) has been determined to be higher, at c. 68.5 kJ/mol. [7] The alpha form is a semiconductor with band gap of c. 2.1 eV. [4]
Iron has five nitrides observed at ambient conditions, Fe 2 N, Fe 3 N 4, Fe 4 N, Fe 7 N 3 and Fe 16 N 2.They are crystalline, metallic solids. Group 7 and group 8 transition metals form nitrides that decompose at relatively low temperatures—iron nitride, Fe 2 N decomposes with loss of molecular nitrogen at around 400 °C and formation of lower-nitrogen content iron nitrides.
