Question
Who has called the smaller particle or the piece “Atomos”?
- Empedocles
- Leucippus
- Democritus
- Both B and C
Hint:
The Greek Philosopher proposed the term atomos.
The correct answer is: Democritus
- Democritus was the scientist who proposed that matter is composed of very small tiny particles called "atomos"
- The Greek philosopher named Democritus was curious to see the result of cutting a piece of matter into the smallest number of pieces so that it cannot be broken any further. He named particles at this point, the atomos.
- The atomos refers to the particles that cannot be divided any further and are thus, known as indivisible.
There is no other element in this universe that is smaller than an atom.
