In chemistry, Dalton came up with the atomic theory upon which modern chemistry is based on today. This is because the Dalton theory allows for much simpler formulas, which was a major advantage for chemists everywhere.
Dalton was an early chemist who believed that the atom was a solid sphere that could not be destroyed or cut into smaller portions.
His atomic theory has five main points:
- all matter is made of atoms, which are indivisible and indestructible.
- all atoms of a given element are identical in mass/properties.
- atoms of a given element are different from those of any other type of element. as a result, atoms of different elements can be set apart from one another by their respective relative atomic weights.
- compounds are formed through combinations of 2 or more kinds of atoms and a given compound always has the same relative numbers of each type of atom.
- rearrangements of the atoms are called chemical reactions.
He came up with his atomic theory by using Joseph Louis Prout's law of definite proportions as a basis and then added his own law of multiple proportions.
