Rutherford explained the nucleus of an atom and Bohr modified that model into electrons and their energy levels. The model also proposed electronic configuration, which explains the arrangement of electrons in circular orbits designated as K, L, M, N, etc. The line spectra of hydrogen atom had many discrete lines. Bohr model states that most of the atomic mass is in the central nucleus, which contains protons and, that electrons are arranged in definite energy levels or shells, resulting in electron line spectrum. He kept the positively charged nucleus part the same but he further defined the negatively charged space surrounding it as electrons of tiny comparative mass that orbit the central core in defined rotational orbits similar to the solar system (planets around the Sun).
