Web28 de dez. de 2024 · In 1913, Niels Bohr revised Rutherford’s model by suggesting that the electrons orbited the nucleus in different energy levels or at specific distances from the nucleus. Therefore, electrons cannot be arranged at random, but they must have fixed levels of energy within each type of atom. WebThe modern periodic table lists the elements in order of increasing atomic number (the number of protons in the nucleus of an atom). Historically, however, relative atomic masses were used by scientists trying to organise the elements.
