In 1913, Rutherford started using the term "nucleus".

Conducting a series of alpha particle scattering experiments through 1917 on various gases like air, hydrogen and nitrogen, Rutherford established the fact that the nucleus of the atom had to be positively charged.

Originally when Geiger had reported strong deflection of alpha particles (refuting the Thomson pudding model), Rutherford was stunned.

In his words:
"It was quite the most incredible event that ever happened in my life.

It was almost as incredible as if you fired a 15-inch shell at a piece of tissue paper and it came back and hit you.

On consideration, I realized that the scattering backward must be the result of a single collision.

When I made calculations I saw it was impossible unless you took a system in which the greater part of the mass of the atom was concentrated in a minute nucleus.

It was then that I had the idea of an atom with a massive centre carrying a charge".

The Geiger-Marsden experiments is one of the seminal and landmark scientific event of our species and can be argued to segregate Homo from the genus Pan.

It deepened our understanding of how matter in the universe is structured at its fundamental level.

Of course, Rutherford's model is neither complete nor totally accurate.

In fact, as per the classical Newtonian physics, it was an impossible model.

This only spurred the great minds into greater physics.

Good night mon ami and my fellow cousin ape.
