Model covalent bonding with moving electrons!
Covalent bonding is easy to understand with our unique molecular model that shows how electrons behave during bond formation.
Download and print as many times as you want - forever at no extra cost!
Your students first build their easy to make paper models of atoms and electrons. They use these to form molecules by sharing electrons between the atoms. The differently coloured electrons make it easy to see how the covalent bonds are formed.
The models can then be used to show molecular hydrogen, oxygen, nitrogen, chlorine. It can also be used to make water, hydrogen chloride, carbon dioxide, methane, ethane, ethene and ammonia.
Optional extension to show co-ordinate bonds in the ammonium ion is included.
Includes full colour Powerpoint presentation!
Takes about 30 minutes! Model atom diameter 10cm/4in
