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.
In 1879, Albert Einstein was born in Ulm, Germany. He completed his Ph.D. at the University of Zurich by 1909. His 1905 paper explaining the photoelectric effect, the basis of electronics, earned him the Nobel Prize in 1921. His first paper on Special Relativity Theory, also published in 1905, changed the world.
