Silver nitride

Silver nitride is an unstable inorganic compound of silver and nitrogen, usually represented by the formula Ag₃N. It is highly explosive and can decompose violently.

Decomposition reaction: A chemical reaction in which one compound breaks into two or more simpler substances. Silver nitride can break down violently into silver and nitrogen-containing products.
Nitride: A compound or ion containing nitrogen in a formally reduced state, often with nitrogen assigned oxidation state −3. The name places Ag₃N among nitrogen compounds, though its actual structure and composition are uncertain.
Ammonia: A colorless compound of nitrogen and hydrogen with formula NH₃. Ammonia is involved in classical reports of forming silver nitride from silver salts.
Explosive hazard: The risk that a material can release energy rapidly through explosive decomposition or reaction. Silver nitride matters primarily because even small deposits may present an explosive hazard.
Nitrogen: A chemical element with symbol N and atomic number 7, commonly found as diatomic nitrogen gas. Nitrogen is the other element in Ag₃N and can form N₂ during decomposition.
Oxidation state: A formal charge assigned to an atom in a compound under a set of bookkeeping rules. Oxidation-state bookkeeping helps interpret proposed ionic descriptions of silver nitride.
Tollens' reagent: An ammoniacal silver(I) solution used in a chemical test for aldehydes and related reducing substances. Residual ammoniacal silver solutions can form explosive silver-containing deposits on standing.
Chemical safety: Practices and principles for preventing harm during the handling, storage, and disposal of chemicals. Its sensitivity makes hazard prevention central to any discussion of silver nitride.
Silver: A lustrous, electrically conductive chemical element with symbol Ag and atomic number 47. Silver atoms make up three quarters of the atoms in the nominal Ag₃N formula.
Ionic bonding: Chemical bonding arising from electrostatic attraction between oppositely charged ions. A simple ionic model is often invoked to rationalize the nominal Ag₃N formula.
