Are substances which
- cannot be broken down by chemical means to simpler form
- Are particles which
- ATOMS
- Are the smallest physical units of chemical identity
- Were initially a philosophical concept
- Made plausible by
- Daltons Automic Theory
- Made plausible by
- Were shown by Rutherford,s 1911 experiment
- to be
- mostly empty space
- in which
- negative charge is spread throughout the atomic volume
- shown later to contain
- ELECTRONS
- shown later to contain
- most of the mass is concentrated in a tiny NUCLEUS carrying a possitive charge
- charge defines

- ISOTOPES
- whose abundances determine the
