Nitrides are a large class of compounds with a wide range of properties and applications.[1]. What is plot of the story Sinigang by Marby Villaceran? [5][6], Nitrides of heavier members from group 11 and 12 are less stable than copper nitride, Cu3N and Zn3N2: dry silver nitride (Ag3N) is a contact explosive which may detonate from the slightest touch, even a falling water droplet.[7]. The nitrides of the alkaline earth metals have the formula M3N2 are however numerous. Only one alkali metal nitride is stable, the purple-reddish lithium nitride (Li3N), which forms when lithium burns in an atmosphere of N2. 2008-05-24 07:22:11. The name nitrite can also refer to organic compounds with the -ONO group, which are esters of nitrous acid. Who is the longest reigning WWE Champion of all time?

Like carbides, nitrides are often refractory materials owing to their high lattice energy which reflects the strong attraction of "N3−" for the metal cation. Find an answer to your question What is the symbol and valency of Nitrate 1. This structure is like hexagonal diamond (lonsdaleite) where every carbon atom occupies a tetrahedral site (however wurtzite differs from sphalerite and diamond in the relative orientation of tetrahedra). 1 decade ago. Answer Save. 0. Compounds where nitrogen is not assigned −3 oxidation state are not included, such as nitrogen trichloride where the oxidation state is +3; nor are ammonia and its many organic derivatives. Oxygen is more reliable in the charge of its ion, so with 2 oxygen atoms in the nitrite ion, oxygen contributes -4 to the overall charge. Examples include Be3N2, Mg3N2, Ca3N2, and Sr3N2.
