3. Atoms cannot be created or destroyed.

4. Atoms of different elements may combine with each other in a fixed, simple, whole number ratios to form compound atoms.

5. Atoms of same element can combine in more than one ratio to form two or more compounds.

6. The atom is the smallest unit of matter that can take part in a chemical reaction.

Answer 2

3. Atoms can neither be created nor destroyed during physical change or a chemical reaction.
4. All atoms of a particular element are identical in all respect.
5. Atoms of different elements have different masses,sizes,and also chemical properties
6. Atoms are the smallest particles of matter which can take part in chemical combinations.
7. Atoms of the same or different elements combine in small whole number ratios to form molecules of a compound.
