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. Albert Einstein was born on March 14, 1879 in Ulm, the first child of the Jewish couple Hermann and Pauline Einstein, nÃ©e Koch. In June 1880 the family moved to Munich where Hermann Einstein and his brother Jakob founded the electrical engineering company Einstein & Cie. Albert Einstein's sister Maria, called Maja, was born on November 18, 1881. Einstein's childhood was a normal one, except that to his family's irritation, he learnt to speak at a late age.
