Here is your answer mate..!!!

In 1808, John Dalton described the atomic structure. This theory was given on the basis of chemical combination. Following are the main points of this theory:--

1). Each substance is made up of small particles which are called atom.
2). Atoms are invisible.
3). All the atoms of an element have similar properties like mass, size etc.
4). Atoms of different elements have different properties like mass, size, etc.
5). Atoms of different elements combine in whole number ratios to form molecule.
6). A chemical reaction can neither create an atom nor destroy an atom.

Answer 2

Answer:

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.
