Atomic Structure. Atoms are the components that make up all elements. Atoms are made up of three types of sub-atomic particles – protons, neutrons, and electrons. Protons and neutrons make up the nucleus, where most of the mass is concentrated. Electrons orbit the nucleus in shells.

The Bohr model was the first to propose quantum energy levels, where electrons orbit the nucleus at predefined distances and must overcome an energy barrier to move into a new orbital.
WebThis model explained the observed spectra of atoms, but it could not explain the stability of the atom. The Bohr model, proposed by Niels Bohr in 1913, is an improvement on the Rutherford model. It introduces the concept of quantization, which states that the energy of the electrons in an atom is not continuous, but rather exists in discrete energy levels.
