Question
are these answers correct according to the video The History of Atomic Chemistry: Crash Course Chemistry #37 1. For Leucippus & Democritus theory of Atomos, what 3 examples did the The History of Atomic Chemistry Video give for what they thought?
Type Answer Here:
Water: They thought that water could be divided into smaller and smaller pieces until eventually, you would reach the smallest indivisible piece.
Air: They believed air, like water, could be divided down to a point where it would become indivisible.
Fire: They theorized that fire was made up of atoms that could not be divided further.
2. For the 3 examples given, what properties did Leuciipus & Democritus think that they have for each of them?
Type Answer Here:Water: Would have smooth atoms, because it’s fluid and flows easily.
Air: Would have round, smooth atoms that would easily move around one another.
3. According to the video, after Leucippus & Democritus theory was developed, when was the next major development?
Type Answer Here:The next major development occurred around 2,000 years later with John Dalton in the early 1800s.
4. Who took the discharge ray further, and explain how?
Type Answer Here:J.J. Thomson took the discharge ray further by using a cathode ray tube to experiment with electricity passing through gases. He demonstrated that the rays were made of negatively charged particles, later named electrons.
5. What did the scientist who discovered electrons originally name them?
Type Answer Here:J.J. Thomson originally named them corpuscles before they were known as electrons.
6. What did Ernest Rutherford discover and how did he perform the experiment for his discovery? Explain in detail.
Type Answer Here:Ernest Rutherford discovered the nucleus. He performed the gold foil experiment, where he shot alpha particles at a very thin sheet of gold foil. Most particles passed through, but some were deflected at large angles. This showed that the atom has a dense, positively charged nucleus, which led to the development of the nuclear model of the atom.
7. In the video Fig. 37.7, who is the scientist and what atomic model is he famous for? Include the name the model is sometimes called according to the video.
Type Answer Here:The scientist in Fig. 37.7 is Niels Bohr, and he is famous for the Bohr model of the atom. This model is sometimes called the planetary model.
8. Who got everyone to understand just how huge and mind blowing the electron problem was?
Type Answer Here:Werner Heisenberg got everyone to understand just how huge and mind-blowing the electron problem was, particularly through his uncertainty principle.
9. What theory did the above scientist propose? Explain the theory.
Type Answer Here:Werner Heisenberg proposed the uncertainty principle, which states that it is impossible to simultaneously know both the position and the velocity (or momentum) of an electron with perfect accuracy. The more precisely one of these properties is known, the less precisely the other can be determined.
10. What is the Quantum Model often called?
Type Answer Here:The Quantum Model is often called the wave mechanical model of the atom.
11. Everyone was sure of their atomic model, according to the video, what is the only way we can be sure?
Type Answer Here:According to the video, experiment is the only way we can be sure of an atomic model. New experimental evidence can either support or disprove the models.
Type Answer Here:
Water: They thought that water could be divided into smaller and smaller pieces until eventually, you would reach the smallest indivisible piece.
Air: They believed air, like water, could be divided down to a point where it would become indivisible.
Fire: They theorized that fire was made up of atoms that could not be divided further.

Here are the answers you've provided. Let’s review them for accuracy based on the themes typically covered in **Crash Course Chemistry #37: The History of Atomic Chemistry**:
1. **For Leucippus & Democritus theory of Atomos, what 3 examples did the The History of Atomic Chemistry Video give for what they thought?**
- **Answer Review**: The examples you've listed may capture the general spirit, but traditionally, Leucippus and Democritus would refer to indivisible particles called "atomos" - in general, they discussed these ideas around all matter rather than giving specific examples like water, air, and fire. They introduced the concept that everything is made of small particles that are not further divisible.
2. **For the 3 examples given, what properties did Leucippus & Democritus think that they have for each of them?**
- **Answer Review**: Your descriptions of the properties are somewhat aligned with their philosophy but may be too specific. They envisioned atoms as having different shapes and sizes based on the properties of the substances they composed (sharp or rough for hard materials, etc.), but they were less detailed on specific molecules like water or air.
3. **According to the video, after Leucippus & Democritus theory was developed, when was the next major development?**
- **Answer Review**: Correct. The mainstream development was indeed around 2,000 years later with John Dalton in the early 1800s.
4. **Who took the discharge ray further, and explain how?**
- **Answer Review**: Correct. J.J. Thomson used a cathode ray tube to explore the nature of these rays and discovered that they were made of electrons.
