Chemistry Department :
S2 Chemistry
Aim of the Course
The course develops and enhances the chemistry knowledge and understanding from
the first year science course. It has been compiled so that a variety of
chemical ideas and practical skills can be learned. The course is arranged into
three parts: Common Gases, Acids and Metals, and Atomic Structure. The course
should allow pupils to be able to make an informed decision when choosing their
Standard Grade options in S2.
