John Dalton’s Atomic Theory of Matter Designed Literally To Explain Why Matter Acts the Way It Does

Atomic Theory of Matter John 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 Matter 1. 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 Matter 3. 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.

Gold

How Atoms Behave Every element has their own UNIQUE atom. Each unique atom has its own unique Characteristics This is why some elements are a gas at room temperature while others are liquids, and still others are solid Every type of atom has its own, unique: – Mass-Attractive Forces -Atomic # – Melting Point-Boiling Point – Freezing & Condensation Point -Flash Point
