Presentation transcript:

DALTON’S ATOMIC THEORY 1803 Read each of the following postulates and determine whether each is True or False

POSTULATE #1 All matter is composed of extremely tiny indivisible particles called atoms.

POSTULATE #2 Atoms of a given element are identical in size, mass, and properties.

POSTULATE #3 Atoms of different elements differ in size, mass and properties.

POSTULATE #4 Atoms cannot be divided, created, or destroyed.

POSTULATE #5 Atoms combine in simple whole number ratios to form compounds.

POSTULATE #6 In reactions, atoms are combined, separated, and rearranged.

POSTULATE #7 Atoms cannot be changed from one to another, or created, or destroyed.
