F)Atoms retain their identity in a chemical reaction.
Answer:A and B
Explanation:
Scientists such as John Dalton continued researching on the same until when Dalton came up with proposals and developed the atomic theory in the year 1808. According to Dalton:
All elements are made up of tiny particles which are indivisible know as atoms.
Atoms of given elements have unique features which are distinguishable from other elements.
All atoms of an element conform to the law of conservation of energy.
Atoms of different elements can be combined in proportions chemically to form a compound.
