On This Day - Jan 18 : Edward Frankland was born

Frankland introduced the theory of valence when he realised that atoms can only form a certain number of bonds to other atoms. He also co-discovered helium (He), pioneered organometallic chemistry, and was a leader in the field of water purification.

Metals

Understanding the properties and reactivity of metals can help to develop students basic understanding of chemical reactions. All the properties of a particular substance depend upon the elements present and how they are bonded to each other. The activities develop such areas as elements, ions, reactivity series, metal extraction, displacement ...
