What did Dalton's atomic theory state and its modifications?

Here are all five listed in the Modern Chemistry text book. I've put the one that have been revised in bold. (numbers 3 and 5)

1. All mater is composed of extremely small particles called atoms.
2. Atoms of a given element are identical in size, mass, and other properties; atoms of different elements differ in size, mass and other properties.
3. Atoms cannot be subdivided, created, or destroyed.
4. Atoms of different elements combine in simple whole-number ratiOS to form chemical compounds.
5. In chemical reactions, atoms are combined, separated, or rearranged.

This list is on page 68 of the Modern Chemistry (2011) textbook, and the explanation is at the bottom of page 69.
