Democritus called the particles from which "stuff" is made -

• atoms

• atomos

• cool

• Bruh

Why do you think most scientists believed Aristotle's theory of wind, water, fire, and earth instead of Democritus?

• Aristotle was more popular.

• Earth, wind, water, and fire made more sense to them.

• They couldn't see atoms but they could wind, water, earth, and fire.

• They were jealous of Democritus because he had come up with the idea.

After John Dalton's work, the atomic theory was -

• accepted by the scientific community.

• still not accepted by the scientific community. They preferred earth, wind, fire, and water,

• banned from being taught in schools.

• proven to be absolutely true.

Match the following

• Democritus

• Proposed the atomic theory

• JJ Thompson

Match the following

• Ernest Rutherford

• Werner Heisenberg
