Leo Szilard invented the atomic bomb in 1933 while studying possible ways to more effectively perform atomic transmutation experiments with neutrons, that he was working on at the tim in London.
An atomic clock is a device based upon Rubidium or Cesium, among others. It is based upon atomic physics using the microwave signal emitted when atoms change energy levels. The first atomic clock was a maser, built in 1949.
May is it - Caesium
The Nobel Prize in Physics 1975 was awarded jointly to Aage Niels Bohr, Ben Roy Mottelson and Leo James Rainwater for the discovery of the connection between collective motion and particle motion in atomic nuclei and the development of the theory of the structure of the atomic nucleus based on this connection.
There was no concrete evidence that led Dalton to propose his atomic theory. He proposed this theory based on logical explanations about the behavior of elements, gases or materials.
Based on the atomic number of lithium there are three protons in a lithium atom.

In 1914 Henry Moseley found a relationship between an element's X-ray wavelength and its atomic number (Z), and therefore resequenced the table by nuclear charge rather than atomic weight. Before this discovery, atomic numbers were just sequential numbers based on an element's atomic weight. Moseley's discovery showed that atomic numbers had an experimentally measurable basis.

It is based on number of protons. Consider an element has 20 protons.Its atomic number is twenty.

yes. based on increasing atomic number
The atomic number is based on the number of protons in the nucleus of the atom?
inductive reasoning
It is true that an atom has a nucleus. As for which model of the atom is thought to be true, at the present time we use a model based upon quantum mechanics which differs significantly from the early Rutherford or Bohr atomic models.
