The word 'Nucleus' is used in two completely different branches of science: Biology (the nucleus of a cell) and Physics/Chemistry (the nucleus of an atom). Let's see who discovered what.
Cell Nucleus (Biology): Discovered by Robert Brown (1831).
Atomic Nucleus (Physics): Discovered by Ernest Rutherford (1911) via the Gold Foil Experiment.
Proton: Discovered and named by Ernest Rutherford (1919).
In Biology, the nucleus is the 'brain' of the living cell, containing the DNA.
In Chemistry and Physics, the nucleus is the incredibly dense, positively charged center of an atom.
Because the atomic nucleus is positively charged, scientists knew there had to be a positive particle inside it.
The nucleus of a biological cell was discovered by the botanist Robert Brown in 1831.
The atomic nucleus and the proton were both discovered by the famous physicist Ernest Rutherford.
