This is because they are all made up of different types of molecules. Molecules are not only made up of different types of atoms but also different ratios. Like in the water example above, a water molecule has 2 hydrogen atoms and 1 oxygen atom.This is written as H 2 O.olecules are not only made up of different types of atoms but also different ratios.

Albert Einstein (/ËaÉªnstaÉªn/; German: [ËalbÉÉÌ¯t ËaÉªnÊtaÉªn]; 14 March 1879 â 18 April 1955) was a German-born theoretical physicist. He developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). Einstein's work is also known for its influence on the philosophy of science.
Einstein was best known as a theoretical physicist, but he also became a less well known inventor. In physics, Albert Einstein is responsible for the discovery of the special and general theories of relativity (E=Mc2), and he did some important work on the photoelectric effect. <br /> <br /> He co-invented a type of refrigerator with no moving parts; patent number 1781541.
