State the modern theory
of Dalton's Atomic Theory
Answers
1) All matter is made of atoms. Atoms are indivisible and indestructible.
2) All atoms of a given element are identical in mass and properties
3) Compounds are formed by a combination of two or more different kinds of atoms.
4) A chemical reaction is a rearrangement of atoms.
Modern atomic theory is, of course, a little more involved than Dalton's theory but the essence of Dalton's theory remains valid. Today we know that atoms can be destroyed via nuclear reactions but not by chemical reactions. Also, there are different kinds of atoms (differing by their masses) within an element that are known as "isotopes", but isotopes of an element have the same chemical properties.
Many heretofore unexplained chemical phenomena were quickly explained by Dalton with his theory. Dalton's theory quickly became the theoretical foundation in chemistry.

Answer:
Acc. to it
☆Matter is made up of extremely small particles called atoms.
☆Atoms of same element are identical in size shape and atomic mass.
☆Atoms of different elements are different in all respect.
☆Atoms of same or different elements are combined together to form different compounds called molecules.
☆When atoms combined with each other to form molecules, they have simple or same multiple proportion.
Atoms can neither be created nor be destroyed.
