John Dalton Biography
ATOMIC THEORY
Dalton's Atomic Theory
2
An element's characteristics are based by the mass of it's own atoms, and last: (Atoms have identical weights, atoms of different elements have weights. These elements are characterized by their atomic numbers).
3
Atoms are unbreakable, and cannot be changed into something different, (A hypothesis from Newton stating elements can't be made, destroyed, or broken into smaller parts.)
4
When elements are combined, their atoms combine simple, as whole-number ratios. (A suggestion that suggested a strategy for determining relative atomic weights from elemental percentages of element compounds.)
