Spotting the difference

Spotting the difference

Particle diagrams comparing an element of single atoms, an element of diatomic molecules, a compound of AB particles, and a mixture containing AB and B2 particles

Chemistry classifies samples by the particles inside them. To decide what a sample is, ask whether all the atoms are the same type, whether different atoms are bonded, or whether different substances are simply together.

Elements, compounds and mixtures Lesson

  1. IGCSE
  2. /Chemistry
  3. /Elements, compounds and mixtures

Step-by-step lessons on CIE IGCSE Chemistry Elements, compounds and mixtures. 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.
