Foundations of Atomic Theory Section 1 The Atom: From Philosophical Idea to Scientific Theory Chapter 3 Foundations of Atomic Theory Law of definite proportions: a chemical compound contains the same elements in exactly the same proportions by mass regardless of the size of the sample or source of the compound Law of multiple proportions: if two or more different compounds are composed of the same two elements, then the ratio of the masses of the second element combined with a certain mass of the first element is always a ratio of small whole numbers

Law of Multiple Proportions Section 1 The Atom: From Philosophical Idea to Scientific Theory Chapter 3 Law of Multiple Proportions

Section 1 The Atom: From Philosophical Idea to Scientific Theory Chapter 3 Democritus 400 BC Theorized that if you were to cut something in half, then cut it in half again and again…. Eventually you would be left with something too small to be cut. Therefore, Democritus gave us “atomos” or “uncuttable” to be the word for the smallest individual particles of a substance.

Dalton’s Atomic Theory Section 1 The Atom: From Philosophical Idea to Scientific Theory Chapter 3 Dalton’s Atomic Theory All matter is composed of extremely small particles called atoms. Atoms of a given element are identical in size, mass, and other properties; atoms of different elements differ in size, mass, and other properties. Atoms cannot be subdivided, created, or destroyed.

Dalton’s Atomic Theory, continued Section 1 The Atom: From Philosophical Idea to Scientific Theory Chapter 3 Dalton’s Atomic Theory, continued Atoms of different elements combine in simple whole-number ratios to form chemical compounds. In chemical reactions, atoms are combined, separated, or rearranged.

Chapter 3 Modern Atomic Theory Section 1 The Atom: From Philosophical Idea to Scientific Theory Chapter 3 Modern Atomic Theory Not all aspects of Dalton’s atomic theory have proven to be correct. We now know that: Atoms are divisible into even smaller particles. A given element can have atoms with different masses. Some important concepts remain unchanged. All matter is composed of atoms. Atoms of any one element differ in properties from atoms of another element.
