Chemical bonding

Episode of Series “Chemical Education Material Study Series”. Explains chemical bonding in terms of electric interactions that cause the bonding in the hydrogen molecule. The release of energy when H atoms combine to form H2 on a platinum surface is shown. This energy change is related to the similtaneous attraction of electrons by two or more nuclei, opposed by electron-electron repulsions. Through animation the quantum mechanical view of electron distribution is portrayed. The bonding interaction between two hydrogen atoms is contrasted to the very weak, non-bonding interaction between two melium atoms. Suitable for upper secondary level.
