== == Atoms were inferred to exist from the observation of "Brownian motion," which is the jittering of dust particles in air or water or some medium as seen through a microscope. The jitter is supposed to be caused by random collisions of atoms or molecules with the dust particles. If the medium were not composed of particles but were a smooth creamy substance without lumps, there would be nothing to make the dust particles jitter.
Watson and crick and the discovery of the double helix
After Rutherford's discovery(Planetary Model), scientists started to realize that the atom is not ultimately a single particle, but is made up of far smaller subatomic particles. Following it research was done to figure out the exact atomic structure which led to Rutherford's gold foil experiment. They eventually discovered that atoms have a positively-charged nucleus in the center. Since electrons were found to be even smaller, this meant that the atom consists of mostly empty space.
The gold-foil experiment led scientists to conclude that an atom's volume is mainly unoccupied.
the discovery of metals led to tools that lasted longer

discovery of the atom's structure
Alpha particle ie doubly ionized helium atom scattering by the gold foil experiment formed the basis for the discovery of nucleus. The experiment was done by Marsden and Geiger but the experimental observation was commented and final conclusion derived by Rutherford.
He believed that the discovery of private property was the start of a long journey down a bad path. he thought that the discovery of private property led to scarcity which led to the need for man to develop reason, reason allowed man to perceive the differences between men, this perception led to the perversion of self-love into vanity, which is the reason for inequality and misery in today's society.

Rutherford's experiment was important because it showed that an atom is mostly empty space. Rutherford gave more detail of the atom's structure.
British Physicist Ernest Rutherford is considered the 'father of nuclear physics' and is credited with splitting the first atom in 1917. He pioneered the Rutherford model of the atom and theorized that the charge of an atom is concentrated into a nucleus. He was able to split the atom in a nuclear reaction between alpha and nitrogen particles which led to the discovery of the proton.
The discovery of radioactivity
The UV rays were entering the surface of earth. This led to discovery of ozone hole.
