1. what are the four parts of dalton’s theory? indicate which parts are no longer accepted as correct

Explanation:

Dalton's atomic theory has four parts. 1. All matter is made of atoms, which are indivisible and indestructible - this is no longer fully accepted as atoms are composed of sub - atomic particles. 2. All atoms of a given element are identical in mass and properties - isotopes show that atoms of the same element can have different masses. 3. Compounds are formed by a combination of two or more different kinds of atoms - still accepted. 4. A chemical reaction is a rearrangement of atoms - still accepted.

Answer:

1. All matter is made of atoms, which are indivisible and indestructible (not fully accepted). 2. All atoms of a given element are identical in mass and properties (not fully accepted). 3. Compounds are formed by a combination of two or more different kinds of atoms (accepted). 4. A chemical reaction is a rearrangement of atoms (accepted).
