• Introduction to Chemistry

  In this session, you will be introduced to studying Chemistry at O-level under the guidance of Mr Choolun.

  Several basic concepts will be covered so as to give a good base to start studying Chemistry.

  The following concepts are discussed and explained:

     ♦ Valencies of Elements

     ♦ The Periodic Table and Elements

     ♦ Reactivity Series of Metals

     ♦ Radicals, their formulae and their valencies

     ♦ Balancing Chemical Equations with several examples

     ♦ Balancing Chemical Equations involving Radicals

     ♦ Displacement Reactions of Metals 

  Notes and homework (on Balancing Equations) are available in the document section of this session
