- I am J.J Thomas and was around in 1897. I made the Plum Pudding model! Dalton's work (atoms are indivisible) inspired me to develop my works.
- J.J Thomas developed the theory that atoms are made up of smaller particles known as subatomic particles. He experimented with cathode ray tubes and discovered cathode rays travel in straight lines. He made an assumption that all matter is neutral and discovered Electrons are subatomic particles with a negative charge.

- I am Ernest Rutherford and I conducted the Gold foil experiment (1911). I also discovered that most of the atom is empty space. (Worked based on J.J Thomas theory and model).
- Ernest Rutherford discovered that the center of the Nucleus is dense an positively charged. During his Gold foil experiment he states that most particles went straight through while others bounced back hitting the nucleus. He is also the creator of the nuclear model
