Bohr used the emmision spectrum of an element.
Rutherford and Soddy proposed the theory of radioactive decay, which explains how unstable atoms undergo spontaneous disintegration and transform into different elements. They also discovered that the process of radioactive decay involves the emission of alpha and beta particles. This theory laid the foundation for our understanding of nuclear physics.
Jj Thompson in 1904.................. Actually it was Ernest Rutherford who Disproved it in 1911. JJ thompson was the creator of the plum pudding theory

According to Thomson's atomic theory, the mass of an atom was special evenly throughout its volume. Errest Rutherford's experiment proved this wrong.
Rutherford's theory proposed that atoms have a dense, positively charged nucleus. This led to the understanding that atoms are mostly empty space with electrons orbiting the nucleus. This laid the foundation for the modern atomic theory, which further developed with the discovery of subatomic particles and the concept of atomic number.
Rutherford and Soddy's theory stated that uranium successively disintegrated to lead. Rutherford discover the proton. He also discovered that the atom is mostly space.

The Atomic Theory
Rutherford's theory is known as the Rutherford model or Rutherford atomic model. It describes the structure of an atom as a dense positively charged nucleus surrounded by orbiting electrons.
D. E. Rutherford has written: 'Introduction to lattice theory' -- subject(s): Lattice theory

Are there elements in the theory that are untestable?
Ernest Rutherford conducted his studies to test J.J Thompsons 'Plum Pudding' theory.
1955
Ernest Rutherford contributed to the atomic theory through his gold foil experiment. He discovered that there was a positively charged central core to the atom and he called it the nucleus.
