Platinum nitride and osmium nitride may contain N 2 units, and as such should not be called nitrides. [11] [12] Nitrides of heavier members from group 11 and 12 are less stable than copper nitride (Cu 3 N) and zinc nitride (Zn 3 N 2): dry silver nitride (Ag 3 N) is a contact explosive which may detonate from the slightest touch, even a falling ...
In the NO − 3 anion, the oxidation state of the central nitrogen atom is V (+5). This corresponds to the highest possible oxidation number of nitrogen. Nitrate is a potentially powerful oxidizer as evidenced by its explosive behaviour at high temperature when it is detonated in ammonium nitrate (NH 4 NO 3), or black powder, ignited by the shock wave of a primary explosive.
3 Ca + N 2 → Ca 3 N 2 3 Mg + 2 NH 3 → Mg 3 N 2 + 3 H 2 (at 900 °C) 3 Zn(NH 2) 2 → Zn 3 N 2 + 4 NH 3. Many variants on these processes are possible. The most ionic of these nitrides are those of the alkali metals and alkaline earth metals, Li 3 N (Na, K, Rb, and Cs do not form stable nitrides for steric reasons) and M 3 N 2 (M = Be, Mg ...
The net charge of an ion is not zero because its total number of electrons is unequal to its total number of protons. A cation is a positively charged ion with fewer electrons than protons [2] (e.g. K + (potassium ion)) while an anion is a negatively charged ion with more electrons than protons. [3] (e.g. Cl − (chloride ion) and OH − ...
Nitrogen trioxide or nitrate radical is an oxide of nitrogen with formula NO 3, consisting of three oxygen atoms covalently bound to a nitrogen atom. This highly unstable blue compound has not been isolated in pure form, but can be generated and observed as a short-lived component of gas, liquid, or solid systems.
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 ]
Sodium azide NaN 3 is the propellant in automobile airbags. It decomposes on heating to give nitrogen gas, which is used to quickly expand the air bag: [7] 2 NaN 3 → 2 Na + 3 N 2. Heavy metal azides, such as lead azide, Pb(N 3) 2, are shock-sensitive detonators which violently decompose to the corresponding metal and nitrogen, for example: [8]
In chemistry, the pentazenium cation (also known as pentanitrogen) is a positively-charged polyatomic ion with the chemical formula N + 5 and structure N−N−N−N−N.Together with solid nitrogen polymers and the azide anion, it is one of only three poly-nitrogen species obtained in bulk quantities.
