what was one reason aristotle rejected the atomic theory proposed by democritus?
he couldnt see atoms with the naked eye.
he believed matter was continuous and made of earth, air, fire, and water.
he thought atoms were alive.
he believed atoms could be divided infinitely.

Explanation:

For the first question, Leucippus and Democritus were ancient Greek philosophers who first proposed the concept of "atomos". Dalton proposed modern atomic theory, Rutherford did work on the atomic nucleus. Newton is known for laws of motion and gravity, Boyle for gas laws. Aristotle and Plato had different views on matter.
For the second question, Aristotle believed in the four - element (earth, air, fire, water) theory of matter which was continuous, so he rejected Democritus' atomic theory. Atoms are too small to see with the naked eye (but that was not Aristotle's main reasoning as he didn't have the technology to check). There's no indication he thought atoms were alive. And he believed matter was continuous (not that atoms could be divided infinitely as he didn't believe in atoms in the first place).

Answer:

(0:35) C. Leucippus and Democritus
