SpletThe nuclear shell model is a theoretical model to describe the atomic nucleus in nuclear physics. The nuclear shell model was proposed by Dmitry Ivanenko in 1932 and further developed independently by several physicists such as Maria Goeppert-Mayer, Eugene Paul Wigner, and J. Hans D. Jensen in 1949. SpletThe atomic model In 1932, James Chadwick discovered the neutron – a particle with no charge in the nucleus of the atom. The modern model of the atom. Today, scientists use …

These clouds are clouds of probability; though we don’t know exactly where the electrons are, we know they’re likely to be found in given regions of space. These regions of space are referred to as electron orbitals.
SpletIn 1911, Ernest Rutherford discovered that at the core of every atom is a nucleus. Atomic nuclei consist of electrically positive protons and electrically neutral neutrons. These are held together by the strongest known fundamental force, called the strong force. The nucleus makes up much less than .01% of the volume of the atom, but typically ...
