Atoms shape everything. The world is made of atoms but the minutiae it has, making atomic models nearly unpredictable. But things are not always impossible as these scientists finally figure out how atoms work.

The first person to discover atom was John Dalton. He stated that atom was an undestructible salt. The Dalton's atomic model - unbreakable sphere - had proven as inaccurate by J.J. Thomson - who invented a new model which had electrons scatter around the sphere. Then later, things had changed. Bohr was the first scientist to discover a new atomic model features the spectra each electron absorbs and proton which lead to the study of electron shells and atomic configuration

In conclusion, atom can't be easily seen and scientists have to come up with a possible model to facilitate the learning of atoms. Micro stuffs wouldn't be exist if the atoms and elements hadn't been discovered.
