The Noble Gases
When breaking down the details of the periodic table of elements, this presentation will explain special characteristics for each of the noble gases. The annotations are quite elementary, so this can easily be used in an introductory...

Mocomi: Molecules
When two or more atoms combine they give rise to a molecule. A molecule can be made up of many atoms of the same element. There are 112 elements known to man, so can you imagine the different permutations and combinations of molecules...

Atoms in Motion: Noble Gases
The ideal gas law is an empirical law; it's a relationship between the pressure in a system of gases to the volume, the temperature, and the number of gas atoms/molecules in the system. This "law" is valid if the gas atoms/molecules are...

Bbc: Gcse Bitesize: Covalent Bonds
A covalent bond is formed between non metal atoms, which combine together by sharing electrons. Covalent compounds have no free electrons and no ions so they don't conduct electricity.
