C. particles of different elements combine in simple whole number ratio
D. all elemets are made of small indivisible particles
Correct Answer:
Option A – atoms can neither be created nor destroyed
Explanation
Postulates of Dalton’s atomic theory can used to explain the behavior of matter:
All matter is composed of small tiny particles called atoms. In Greek the word atom is termed as indivisible. The atoms can not be further broken down.
All atoms are indivisible, indestructible, and unchangeable. Atom of an element cannot be created, divided, destroyed, or split into smaller particles or transformed into atoms of other elements or transformed into other atoms in a chemical reaction. They are simply rearrangement of new compound. Dalton’s atomic theory based this hypothesis on the law of conservation of mass and on centuries of experimental evidence.
