Atomic Theory of Matter

John Daltons Atomic Theory of MatterDesigned Literally To Explain Why Matter Acts the Way It Does

Atomic Theory of MatterJohn Dalton, an English school teacher from the early 1800s, came up with the idea

Gold behaves like gold, because its atoms behave this way

Atomic Theory of Matter1. Each element is composed of extremely small particles called atoms.

2. All atoms of a given element are identical; the atoms of different elements are different and have different properties (including different masses).

Atomic Theory of Matter3. Atoms of an element are not changed into different types of atoms by chemical reactions; atoms are neither created nor destroyed in chemical reactions.4. Compounds are formed when atoms of more than one element combine; a given compound always has the same relative number and kind of atoms.

How Atoms BehaveEvery element has their own UNIQUE atom.Each unique atom has its own unique CharacteristicsThis is why some elements are a gas at room temperature while others are liquids, and still others are solidEvery type of atom has its own, unique:Mass-Attractive Forces -Atomic #Melting Point-Boiling PointFreezing & Condensation Point -Flash Point
