No, Democritus was the first to think of atoms, Dalton thought the atom was an indestructible sphere.
They both proposed the theory that all matter consists of atoms.
Democritus was an ancient Greek philosopher who was a pupil of Leucippus. Democritus suggested that different types of small discrete particles formed all matter. He suggested that the properties of the tiny particles are what determined the property of the matter.
It didn't look like much. Democritus didn't really have a "model" of the atom; he was just the first to suggest that all matter was composed of atoms.
John Dalton. N.B.: John Dalton [born: September 6, 1776; died: July 27, 1844, at age 67] was an English chemist and physicist who claimed matter was made up of tiny particles and that these particles were identical for any given kind of matter. Moreover, he claimed these particles were indivisible and could neither be created nor destroyed in any chemical process, only be altered in the manner they were grouped.
Democritus began the atomic theory. He was the first to theorize that if you keep cutting stuff down smaller and smaller, you will eventually reach the smallest piece possible. He was, however, put down by Aristotle. Aristotle had a larger and stronger following, so people dismissed Democritus as a lunatic.

Democritus
Matter is composed from small particles called atoms.
Democritus, in the 5th century, proposed his version of atomism. States that all matter was composed of small indivisible particles called atoms.
The Greek philosophers Leucippus and Democritus first theorized about atoms. In fact, that's who named them atoms.
Around 400 BC Democritus a Greek philosopher theorized that everything was composed of small indivisible particles he called atoms or "atomos".
Democritus did not do any experiments or provide solid evidence for his theory on the atom. In the 5th century B.C, Democritus proposed an atomic model in which all matter is made up of small indestructible units called atoms.
They both proposed the theory that all matter consists of atoms.
Democritus was an ancient Greek philosopher who was a pupil of Leucippus. Democritus suggested that different types of small discrete particles formed all matter. He suggested that the properties of the tiny particles are what determined the property of the matter.
The word "atom" comes from the ancient Greek "atomos" meaning "uncuttable". The concept of atoms being the smallest part of an element is a natural philosophy that developed in several ancient traditions, and it is therefore difficult to say "who" was the first person to make this claim.
he did many experimeants such as testing the theory of small invisble atoms
It is Democritus (440 B.C.) He proposed the idea that all atoms were small, hard particles made of one material and that everything can be broken down until there is nothing left but atoms. Course, this was long ago, so his theory wasn't exactly thorough enough..
