which of the following is not correct about the discovery of atoms?1 pointplum pudding model is given by JJ Thomsonrutherford is also known as the father of nuclear physicsneutron is discovered by Neil bohrrutherford failed to explain why electron is not losing energy and falling into the nucleus

In 1932, James Chadwick discovered that some particles in the nucleus have no charge at all. He called them neutrons. Electrons (negatively charged particles) have been shown to orbit the nucleus at distances.
