Glossary
Atom - A unit of matter, the smallest unit of an element, consisting of a dense, central, positively charged nucleus surrounded by a system of negative electrons.
Hydrogen - A colorless, highly flammable gaseous element. It is the lightest of all gases and the most abundant element in the universe. It is the first element on the periodic table.
Nitrogen - A nonmetallic element that makes up nearly four-fifths of the air by volume. It occurs as a colorless, odorless gas.
Molecule - The smallest particle of a substance that retains the chemical and physical properties of the substance and is composed of two or more atoms.
Temperature - The degree of hotness or coldness of a body or environment.
Pressure - Force applied uniformly over a surface, measured as force per unit of area.
Pungent Smell - Affecting the organs of taste or smell with a sharp acrid sensation.
Corrosive - Harmful or destructive, having the quality of corroding or eating away.
Azane - Another name for ammonia.
Ammonium Hyrdoxide - When ammonia is mixed with water it produces ammonium hydroxide.
NH4OH - The chemical formula for ammonium hydroxide.
NH3 - The chemical formula for ammonia.
Alkaline - Having the properties of an alkali, or containing alkali; having a pH greater than 7.
Nitric Acid - A colourless or yellowish, suffocating, caustic, corrosive, water-soluble liquid having powerful oxidising properties. It is usually obtained from ammonia.
HNO3 - The chemical formula for nitric acid.
