Ball-and-stick model of butane and its empirical formula

Chemists use symbols and numbers to describe exactly what is happening in a reaction. When dealing with simple molecules, we use two different types of formula depending on the information we need.

Formulae Lesson

  3. /Formulae

Step-by-step lessons on CIE IGCSE Chemistry Formulae. Each one builds up to exam-style questions. Build a solid grasp of atomic structure, bonding and the mole concept early, since these underpin almost every other topic, then move on to the more calculation-heavy quantitative and organic chemistry content.
