atoms
Storyboard Text
- JJ Thomson discovered that the atom contains negatively charged particles in the year 1897. Thomson referred to these negatively charged particles as corpuscles, but scientists later renamed them to become the electrons that we currently refer to.
- The "Plum Pudding" model of the atom is one I created. The raisins in the pudding are represented by the negative electrons, and the positive charge is contained in the dough.
- 1910 was a year when Ernest Rutherford The gold foil experiment produced the nucleus and the protons inside the nucleus. He also disproved Thomson's Plum Pudding in 1911. Rutherfold came to the conclusion that the atom was made up of a small, dense, positively charged nucleus in the middle, surrounded by negatively charged electrons.
- In the experiment, I found that the majority of the particles passed through the gold. The nucleus is the dense center of the atom that I refer to.
- The neutrons are known as such because they are located in the nucleus and are not charged.
- James Chadwick made the discovery of the neutrons inside the nucleus in 1932.
