According to Dalton's Atomic Theory, matter is made up of atoms, which are indivisible and indestructible particles. All the atoms of the same chemical element are equal in mass and properties and different from the atoms of any other element. The compounds are formed by combinations of atoms of different elements. Modern Atomic Theory Indicates that all matter is made up of atoms, and cannot be destroyed or created. Atoms are made of electrons, protons, and neutrons, it is not indivisible but it is the smallest particle that takes part in chemical reactions. The atoms of an element can have variable masses, that is called isotopes. The atoms of different elements can have the same mass number. The bases of the atomic theory were not new, but I contribute to discovering a way to obtain the atomic weight, and also by means of this theory the standard symbols appear for the elements.
