19 fev 1911 ano - Rutherford’s Model of the Atom

Descrição:

The model that was built based off of Rutherford's model was named the "nuclear" model. Rutherford attempted to test Thomson’s model with radioactivity in an experiment using gold foil and a type of radiation called alpha particles. He discovered the existence of a dense, positively charged core in the atom called the nucleus. A Major contribution was his famous gold foil experiment, which was shooting atoms into extremely thin gold foil and seeing where the surrounding circular wall hit. This is how he discovered protons. Rutherford purposed that the nucleus is a very dense, tiny, and positively charged core of an atom. All of the atom’s positively charged particles, called
protons, are contained in the nucleus.
