OK so basically many experiments were done and Ernest Rutherford found that atoms had a positive charge and it contains most of its mass. and for the electron J.J. Thomson found that atoms have a negative charge after a various amount of study and experimentation
Answer:

Answer:
An atom cannot be subdivided into smaller particles. (Option A).
Explanation:
According to Dalton's atomic theory: All matter is composed of tiny particles called as atoms. Some postulates of this theory are given below:
1) An atom cannot be subdivided into smaller particles it means they are indivisible.
2) Different element atoms have different masses, and chemical properties.
3) All atoms which are present in an element are identical in all respects such as mass, chemical properties, etc.
4) Atom cannot create or destroyed in a closed system.
5) The types of atoms, and relative number are constant in a given compound.
