Ammonia Symbol NH₃

For character lookup, Ammonia Symbol resolves to NH₃. NH₃ is the molecular formula for ammonia: one nitrogen atom and three hydrogen atoms. The 3 is written as a subscript. The page is intentionally narrow: This page covers the chemical formula NH₃. It is not the ammonium ion NH₄⁺, a hazard pictogram, or a substitute for a complete substance label. Practical lookup cases for Ammonia Symbol include NH₃ + H₂O ⇌ NH₄⁺ + OH⁻; Concentration of NH₃; Accessible reading: N H three, ammonia; Unicode sequence for Ammonia Symbol: U+004E U+0048 U+2083; HTML decimal: N H ₃. Additional use contexts recorded for NH₃ are Chemistry education; Chemical equations; Laboratory notes; Environmental monitoring. The most relevant mistakes to avoid are Assuming NH₃ has identical metrics or artwork in every font and platform.; Converting NH₃ to an image when selectable text is more appropriate.; Using NH₃ as the only accessible name of an interactive control.; Writing Nh3 with incorrect capitalization. The variant list distinguishes NH₄⁺ Ammonium Related polyatomic ion; N Nitrogen Element symbol; H₂ Hydrogen Molecular hydrogen. One practical question is “How do I copy Ammonia Symbol?” The recorded answer is: Use the Copy button for NH₃, then paste the complete text sequence into the destination application. For copy and paste, retain NH₃ exactly. That preserves U+004E U+0048 U+2083, keeps search intent focused, and prevents a similar-looking mark from replacing Ammonia Symbol.
