Question

The theory of Democritus state that:
A.Everything is composed of “atoms”, which are physically, but not geometrically, indivisible.
B.Between atoms, there lies empty space.
C.There are an infinite number of atoms.
D.All of the above

Answer 1

Hint:The smallest unit of the matter that forms the element is known as the atom. Everything around us consists of the atoms only such as solids, liquid and gas and the atoms are very small in size further they have the constituents such as into electrons, protons and neutrons.

Complete step by step answer:
Democritus used the atoms and voids terms to explain the concept of the universe. Initially atoms were thought to be indivisible and it was thought that there are large empty spaces inside the atom known as voids. Atoms are infinite in number; they are physically indivisible but not geometrically. He emphasised on the concept that everything in the universe is connected with the one big and unchangeable thing. Initially other philosophers did not agree with his views and took his concepts and perceptions very lightly in a casual way.
He further extended his theory putting forth the view that the atoms come in different sizes, shapes and mass and these are the differentiating properties of the atoms. The properties like colour and taste are not related with the properties of the atom and they are not the main part of the theory he suggested. Thus the main points in put forth in his theory are:
Everything around us is composed of atoms.
Atoms are indivisible physically but not geometrically.
There are empty spaces in an atom and are known as void.
The number of the atoms around us are infinite in number.
Thus the option D. All of the above is the correct answer.


Note:
The first complete attempt to explain the concept of matter in terms of atoms and their properties was made by Dalton. The theory was put forward in two parts where the first part emphasis on the notion that matter is made up of atoms which are indivisible and the next part adds on that the atoms of an element are identical in mass and properties.
