Highlights included the discovery of the atomic nucleus in 1911, Henry Moseley's physical explanation of the different properties of chemical elements and the consequent Rutherford-Bohr model of the ...

Acceptance of this model grew after it was modified ... in creating chemical weapons in World War I. Rutherford died two years before the discovery of atomic fission. "All science is either ...

In 1912 Bohr joined Rutherford. He realized that Rutherford's model wasn't quite right. By all rules of classical physics, it should be very unstable. For one thing, the orbiting electrons should ...

Rutherford’s discovery is now often described as ‘splitting the atom’ in popular accounts, but this should not be confused with the process of nuclear fission discovered later in the 1930s. Between ...

This "Rutherford model" would form the basis of modern atomic ... was a fundamental building block of atoms. His discovery of ...

New evidence The discovery of electrons ... New evidence In-depth work on Rutherford's model showed it had limitations. The electrons should just spiral in towards the positive nucleus.
