WebDalton proposed that every single atom of an element, such as gold, is the same as every other atom of that element. He also noted that the atoms of one element differ from the atoms of all other elements. Today, we still know this to be mostly true. A sodium atom is different from a carbon atom. WebMolecules are made of atoms, which are made of subatomic particles (protons, neutrons, electrons), which are in turn made of quarks, which are also particles.
