When an electron absorbs a photon, its energy increases because the photon transfers its energy to the electron. The photon ceases to exist as a discrete particle and its energy is absorbed by the electron, causing it to move to a higher energy level.
Hund's Rule states that within a sublevel, electrons will fill empty orbitals before pairing up. This is to maximize the spin of the electrons and stabilize the atom. It helps to explain the arrangement of electrons in an atom's electron cloud.
Niels Bohr proposed the model of the atom where electrons move around a central nucleus in fixed orbits. This model helped explain the stability of the atom and the discrete energy levels of electrons.
Rutherford's model of the atom was incomplete. He proposed a model in which electrons orbit the positively charged nucleus like planets around the sun. However, this model failed to explain the stability of the atom and the energy levels of electrons. It was later improved upon by Niels Bohr's model, which incorporated quantum mechanics concepts to explain these phenomena.
The Bohr model
The major shortcoming of Rutherford's model of the atom did not explain how the atom's negatively charged electrons occupy the space surrounding its positively charged nucleus. Rutherford's model included a small central nucleus of positive charge surrounded by a cloud of electrons.
