Question

What did Democritus believe an atom was?

Answer 1

We need to know when Democritus was brought into the world in Abdera, Thrace, around $460BC$ , despite the fact that there are conflicts about the specific year. His accurate commitments are hard to unravel from those of his guide Leucippus, as they are frequently, referenced together in messages.

Complete answer:
We have to know that, their theory on atoms, taken from Leucippus, bears a passing and fractional similarity to the nineteenth century comprehension of nuclear design that has driven some to view Democritus as to a greater degree a researcher than other Greek logicians; notwithstanding, their thoughts laid on altogether different bases. Generally disregarded in antiquated Athens, Democritus is said to have been disdained such a great amount by Plato that the last wished the entirety of his books consumed. He was in any case notable to his kindred northern-conceived logician Aristotle and was the educator of Protagoras.
We can see Democritus to be the "father of present day science". None of his compositions have endured; just sections are known from his immense assortment of work.
Leucippus is thought to have started the nuclear way of thinking. His acclaimed devotee, Democritus of Abdera, named the structure squares of issue atoms, which means in a real sense "unbreakable," around $430BCE$ . Democritus accepted that particles were uniform, strong, hard, incompressible, and indestructible and that they moved in endless numbers through void space until halted.

Note:
We have to know that, the idea of the particle that Western researchers acknowledged in a wide diagram from the $1600's$ until around $1900$ began with Greek scholars in the fifth century $BCE$ . Their hypothesis about a hard, indissoluble principal molecule of nature was supplanted gradually by a logical hypothesis upheld by test and numerical allowance.
