In this fun and engaging online lesson, students differentiate between elements and compounds on the most basic level while having fun "encoding" the Periodic Table.

Try these five multiple-choice questions that help students review atoms, elements, and compounds. Each question has a hint and a self-checking feature.

This audio book, narrated by author Mark Bishop, describes the relationship between the masses of elements and compounds. Steps for the conversion process are given. Also find links to tutorials and animations for other chemistry sections.
