Atoms and Molecules

Detailed Key Concepts:

• - Law of Conservation of Mass: Mass is neither created nor destroyed during a chemical
reaction.
• - Law of Constant Proportions: A chemical compound always contains the same
elements in the same proportion.
• - Dalton’s Atomic Theory explains matter in terms of atoms.
• - Atomic mass and molecular mass are calculated based on atomic weights.
• - Avogadro number: 6.022 × 10²³ particles in one mole of a substance.
