ammonium
Ammonia plus hydrogen
Ammonium is a positively charged ion (NH₄⁺) formed when ammonia combines with hydrogen.
It appears in chemistry and agriculture, particularly in fertilizers: ammonium nitrate, ammonium sulfate.
Ammonium compounds are nitrogen sources for plants and ingredients in explosives and cleaning products.
