# Chemistry

Chemistry is the study of composition and properties of matter, and deals with how chemical elements and compounds interact with each other.

The IB Chemistry course covers 11 topics for SL students, and an additional 10 topics for HL students. Each HL topic (topics 12 through 21) corresponds to each SL topic (topics 1 through 11), and each of these HL topics essentially amounts to a more in-depth look at the same topic covered in its SL equivalent. Once the core topics have been covered, students and their teacher collectively decide which one of the four available options to cover as their final topic of the curriculum.
