GCSE Chemistry Key Words Empirical formula: The smallest whole number ratio of atoms of each element in a compound. *Fine particles:-Fine particles (PM 2.5) have diameters between 100 and 2500 nm (1 x 10 7 m and 2.5 x 10-6 m). Fullerenes: Fullerenes are molecules of carbon atoms with hollow shapes. The structures
Chemistry: The study of matter, its composition and properties, and the changes it undergoes. Matter: Anything that has rest mass. To develop this topic we need to define the atom, the basic unit of common matter. Atom: A neutral particle consisting of a nucleus containing most of its mass, and electrons.
