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

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

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

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

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

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

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

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