The first lesson introduces the states of matter and atomic structure. In the next lesson we progress to relative formula mass and chemical equations - don't be put off by these as everything is very carefully explained!

Excellent so far, very impressed and I'm learning so much. Sound Quality needs to be better though and reference to periodic table should show it more often.
Very clear and detailed explanations covering all aspects. The downloadable resource is an unidentifiable file type and cannot be opened.
