Pasted below is his 5 theory's and all of them are the building blocks of chemistry today.
1. Matter is made up of atoms that are indivisible and indestructible.
2. All atoms of an element are identical.
3. Atoms of different elements have different weights and different chemical properties.
4. Atoms of different elements combine in simple whole numbers to form compounds.
5. Atoms cannot be created or destroyed. When a compound decomposes, the atoms are recovered unchanged.
A compound is a combination of a different elements to form a new substance. The new substance may well have different properties to that of the composing elements. When a compound is made of 50% sulphur and 50% oxygen, it's empirical formula is SO (sulphur oxide). In other words, there is one sulphur atom and one oxygen atom - each consists of 50% of the overall molecule.
