• Haber processBroader topic: It is the process's product and the feedstock for many downstream products.

• Hydrogen storageCompared with: Ammonia can transport hydrogen chemically, but using it requires synthesis or decomposition.

• HydroxideCompared with: Ammonia accepts protons without containing hydroxide as part of its formula.

• Lone pairBroader topic: Nitrogen’s lone pair gives ammonia its pyramidal geometry and basicity.

• NitrificationRelated: Microbes generally oxidize ammonia, whose availability depends on pH and temperature.

• Potassium hydroxideCompared with: Unlike KOH, ammonia is a weak molecular base rather than a fully dissociating ionic hydroxide.

• Conjugate acidCompared with: Ammonia accepts a proton to form ammonium, its conjugate acid.

• Uric acidCompared with: Ammonia is more soluble and toxic than uric acid, but requires abundant water for safe excretion.

• Urea cycleRelated: The cycle removes ammonia before its accumulation becomes toxic.

• Bond angleBroader topic: Its H–N–H angles are about 107°, smaller than the tetrahedral ideal.

• Chemical industryBroader topic: It is a major industrial product whose manufacture links natural gas, nitrogen, and fertilizer supply.
