In 1911, Rutherford, Marsden and Geiger discovered the dense atomic nucleus by bombarding a thin gold sheet with the alpha particles emitted by radium. Rutherford and his students then counted the number of sparks produced by these alpha particles on a zinc sulphate screen. From this observation, they concluded that almost all the atomic matter was concentrated in a tiny volume situated at the atome center, the atomic nucleus.

The discovery of the nucleus led Niels Both to make the first theoretical representation of the atom. The ‘quantum mechanical’ revolution, culminating in the later developments made by Erwin Schrodinger, laid the foundations for our understanding of the infinitely small.

The study of the chemical properties of the elements in the uranium-radium family showed that radium D, radium B and radium G have the same chemical properties as lead (*). In 1913, Frederick Soddy concluding that these elements all belong in the same square of Mendeleyev’s periodic table, introduced the concept of ‘isotopes’, and won the Nobel Prize for Chemistry in 1921.

Answer 2

Answer:

hope it helps you

Explanation:

The nucleus was discovered in 1911, as a result of Ernest Rutherford's efforts to test Thomson's "plum pudding model" of the atom. ... In his plum pudding model, Thomson suggested that an atom consisted of negative electrons randomly scattered within a sphere of positive charge
