A compound radical, NH4, having the chemical relations of a strongly basic element like the alkali metals.

A form of nitrogen that is commonly found in the soil.

(NH 3 & NH4+): Ammonia is a gaseous, alkaline compound of nitrogen and hydrogen (NH3) . High ammonia levels in an aquarium are caused by the absence of nitrifying bacteria (nitrosomonas). For more information about Ammonia and the nitrogen cycle, see article 0009 - Introduction to the Nitrogen Cycle.

the ion NH4 derived from ammonia; behaves in many respects like an alkali metal ion

The chemical ion NH+4.

Anion (NH4+) derived from ammonia (NH3)

Positive ion with the formula NH4+ that forms when ammonia dissolves in water. It adds non-natural alkalinity to the water.

One form of nitrogen that is usable by plants.

The ionic form of ammonia nitrogen that is usable by plants. See Also ammonia.

The ammonium cation is a positively charged polyatomic cation of the chemical formula 4+. It has a molecular mass of 18.04 and is formed by protonation of ammonia (NH3). Ammonium and aminium are also general names for positively charged or protonated substituted amines and quaternary ammonium cations N+R4, where one or more hydrogen atoms are replaced by organic radical groups (which could be symbolized as R).
