Atoms, Elements and Compounds
Atomic theory and its associated findings form the basis for modern chemistry. Building on past explorations using various substances and the particle model of matter, students should become familiar with the basic constituents of atoms and molecules, with chemical symbols themselves, and with common elements and compounds. A strong connection should develop between students’ basic ideas about chemistry and related examples in their own lives.
Key Ideas
1. Atomic theory explains the composition and behaviour of matter.
2. Elements are the building blocks of matter.
3. Elements combine to form compounds.
