Answer to Problem 2.8P
According to Democritus’s atomic theory, all matter is made up of very small particles and he called these particles atoms. According to the Dalton’s atomic theory, all matter is made of tiny indivisible particles which Dalton called atoms.
Explanation of Solution
According to Democritus’s atomic theory, all matter is made up of very small particles and he called these particles atoms. Atom word is derived from the Greek word ‘atmos’ means not to cut. According to the Dalton’s atomic theory, all matter is made of tiny indivisible particles which Dalton called atoms.
The main difference between Democritus’s atomic theory and Dalton’s atomic theory is Dalton based his theory on evidence while Democritus had no evidence to prove his theory.
According to Democritus’s atomic theory, all matter is made up of very small particles and he called these particles atoms. According to the Dalton’s atomic theory, all matter is made of tiny indivisible particles which Dalton called atoms.
