John Dalton (sep 6, 1766 – jul 27, 1844)
Description:
1766-1884 AD in England
Dalton developed an atomic theory of which many aspects stand true today. This theory included that:
- Elements are made of atoms, which are tiny particles, too small to see.
- All atoms of a particular element are identical.
- Atoms of different elements have different properties: their masses are different, and their chemical reactions are different.
- Atoms cannot be created, destroyed, or split.
- In a chemical reaction, atoms link to one another, or separate from one another.
- Atoms combine in simple whole-number ratios to form compounds.
Dalton also developed early diagrams of how a water molecule positions itself in ice, which includes a slight bend
