The First Atomic Structure was proposed by John Dalton, Dalton viewed atoms as "tiny solid balls"
In 1897 J.J. Thompson who discovered the eletrons, the first scientist to show that atom was made of smaller things, To get the number of electrons....the number of protons is same as electrons
In 1911 Ernest Rutherford Discovered the Protons and the Nucleus by performing the Gold Foil Experiment, He said that the Center of Atom is the Nucleus, The number of the protons is the atomic number
In 1913 Niels Bohr improved Rutherford's model, He proposed that electrons move around the nucleus in specific layers. 'Every atom has a specific number of electron shells
In 1932 James Chadwick discovered the neutrons, He discovered particles with no charge, The neutrons are found inside the nucleus, To get the number of Neutrons you subtract the Atomic number from the mass
The Modern Atomic Model which has electrons moving in a cloud, The location of the electron is unpredictable
