I think I might have gotten htese two incorrect
atoms are small ahrd particles - I put Democritius
An atom is the smallest peice of matter - I put Dalton
Are these correct
#1 I don't know. The idea of atoms being small hard particles is hard for anyone to explain, for example, why oxygen gas isn't hard or nitrogen gas isn't hard.
#2.I would answer Democritus for this although he had no evidence to prove what he thought.
The first statement, "atoms are small hard particles," is indeed associated with the Greek philosopher Democritus. He proposed the concept of atoms as indivisible and indestructible particles that compose all matter. Therefore, your answer of Democritus for this statement is correct.
However, the second statement, "an atom is the smallest piece of matter," aligns with the atomic theory proposed by John Dalton. According to Dalton's theory, atoms are indivisible and indestructible units that make up all elements. So, if you chose Dalton as your answer for this statement, you are correct.
To recap, your answer of Democritus for the first statement is correct, and your answer of Dalton for the second statement is also correct. Nice job!
