The history of science in understanding the structure of the atom has been a long journey. First proposed by Democritus in the 5th century B.C., the atom has been refined and reinterpreted by scientists throughout the centuries. In the early 1900s, Ernest Rutherford proposed the nuclear model of the atom, and Niels Bohr later expanded upon this theory. #Atom #HistoryOfScience #Democritus #ErnestRutherford #NielsBohr #StructureOfTheAtom #AtomicTheory #AtomicModel #Atomism #AtomicStructure #NuclearModel
