1. Chemical abbreviations are abbreviated chemical substances formatted into few or more letters.

   • Example: Copper sulphate - CuSO4
     • Occasionally numerical letters are introduced into the abbreviation to show equal balanced atoms within the chemicals mixtures.

2. Metals and non-metals have typically similar properties such as...

   • Non-metals have a low melting-point whereas metals have high melting-points
   • Modern technology is now evolving using indium, gallium and antimony for smart phone chargers, and are now in short supply

3. Atoms are the smallest particle of the chemical element - constructing many and all chemical elements ever formed

   • Also introducing molecules - a group of bonded atoms
