Chemistry (The Composition of an Atom)

posted by .

In 1808, John Dalton wrote his atomic theory of matter. The following is a list of points from that theory. If it is still considered true today, label it true. If it is not considered true today, label it false.

1)Atoms cannot be subdivided.

2)Atoms cannot be created or destroyed in a chemical reaction.

3)All atoms of a given element are identicle in size mass and other properties.

4)All matter is composed of extremely small particles called atoms.

5)Atoms of different elements combine in hole number ratios to make compounds.

6)In chemical reactions, atoms are combined, separated or rearranged.

    Do you have any thoughts? We would like to hear about them instead of simply giving you the answers.
    Number 1 may not be worded very well. I CAN divide atoms in electrons, protons, neutrons, etc BUT I can't subdivide atoms without changing the kind of element.
