In 1911 the existence of the atomic nucleus was discovered by Ernest Rutherford through his interpretation of the gold foil experiment conducted two years earlier by Hans Geiger and Ernest Marsden. In 1932 Dmitry Ivanenko proposed the proton-neutron model of the nucleus.

1. Atoms are made from the atomic nucleus (protons plus neutrons) and electrons.2. For the discovery of electrons is credited J. J. Thomson in 1897.
No one proposed it. It IS about the atomic number.
He formulated his atomic model (electrons orbiting the nucleus) in 1913.
an electrical neutral particle from the atomic nucleus
Marie and Pierre Curie did not discover the atom. John Dalton is credited with the discovery of the atom and J.J. Thomson with the discovery of the electron.

J.C. Adams and U.J.J. Le Verrier are credited with the mathematical discovery and D'arrest and Galle are credited with the observational discovery.

Henri Becquerel was a French scientist who was credited for the discovery of radioactivity. He was credited in 1896.

Opinions vary. The discovery of the atomic nucleus ("most of the atom is empty space")
The atomic number is the number of protons in a nucleus.
The atomic number is equal to the number of the protons in the atomic nucleus.
