Return to TASIS (First Week of Spring Semester)

In class all week, we have reviewed the rules for naming ionic and covalent compounds as well as acids and bases.

Each day students were asked to review the list of polyatomic ions given to them before the winter break.

Friday will be the first test of the semester on Chemical Nomenclature (naming).

Please review the answers to the practice test (below), this website for games on chemical naming, and the jeopardy game (below)
