The nitride ion is very very gay and retarded A nitride (compound) is a compound that has nitrogen with more electropositive elements. General Name, Symbol, Number nitrogen, N, 7 Chemical series nonmetals Group, Period, Block 15, 2, p Appearance colorless Atomic mass 14. ... An electropositive atom, or element, is one that easily loses electrons. ...

Examples

lithium nitride (Li₃N)
boron nitride (BN)
titanium nitride (TiN) - often used as a coating on metals to provide resistance to wear
Also forms the covalent compound Nitrogen trifluoride, NF₃ (N^3- + F^-)

See category for a bigger list. Lithium nitride is a compound of lithium and nitrogen with the formula Li3N. It is the only stable alkali metal nitride. ... Boron nitride is a binary chemical compound, consisting of equal proportions of boron and nitrogen, with formula BN. Structurally, it is isoelectronic to carbon and takes on similar physical forms: a hexagonal, graphite-like one, and a cubic, diamond-like one. ... TiN coated drill Dark gray TiCN coating on a Gerber pocketknife Titanium nitride (TiN) is an extremely hard (~85 Rockwell C Hardness or ~2500 Vickers Hardness)1, ceramic material, often used as a coating on titanium alloy, steel, carbide, and aluminum components to improve the substrates surface properties. ... Covalent bonding is a form of chemical bonding characterized by the sharing of one or more pairs of electrons between atoms, in order to produce a mutual attraction, which holds the resultant molecule together. ... Nitrogen trifluoride, NF3, is a colorless, toxic, nonflammable, corrosive gas shipped in cylinders at high pressure. ...

Discussion

Some nitrides are salt-like compounds, but many are inert compounds similar to carbides. A magnified crystal of salt In chemistry, salt is a term used for ionic compounds composed of positively charged cations and negatively charged anions, so that the product is neutral and without a net charge. ... Carbide In chemistry, Carbide confusingly refers to three different things: 1. ...

An unexpected discovery could yield a full spectrum solar cell (1378 words)
	With a band gap of 3.4 eV, gallium nitride emits invisible ultraviolet light, but when some of the gallium is exchanged for indium, colors like violet, blue, and green are produced.
	At first glance, indium gallium nitride is not an obvious choice for solar cells.
	Two layers of indium gallium nitride, one tuned to a band gap of 1.7 eV and the other to 1.1 eV, could attain the theoretical 50 percent maximum efficiency for a two-layer multijunction cell.

III-V Nitride Semiconductors for High-Performance Blue and Green LEDs (5464 words)
	Considerable efforts to produce and characterize the nitrides began in earnest more than 30 years ago at a number of notable research facilities, such as ATandT Bell Laboratories, IBM Thomas J. Watson Research Center, and RCA, because of the potential for producing surface acoustic wave devices, blue lasers, and LEDs.
	A second problem for growing III-V nitride films is the lack of a suitable substrate that matches the lattice constant and thermal-expansion coefficient of the GaN films.
	It appears that dislocations in III-V nitrides are not associated with electrically active defects that would act as effective nonradiative recombination centers and effectively limit the lifetime of minority carriers.
