Name four out of the eight points that Daltons theory had
What is -All matter is made of atoms, which are particles that are too small for us to see -Each element has its own kind of atom, with its own particular mass. -All atoms of any one element are identical -Compounds are created when atoms of different elements combine in a specific ratio -Atoms cannot be created, destroyed, or subdivided during chemical changes -Matters must contain positive and negative charges -Opposite charges attract, and like charges repel. -Atoms combine to form the particles of a compound because of the electrical attraction between charged atoms
