Question

explain the fundamental ideas in daltons atomic theory ​

Answer 1

Explanation:

1

Elements are composed of extremely small particles called atoms that are indivisible and indestructible

2

All atoms of a given element are identical; they have the same size, mass, and chemical properties

3

Atoms of 1 element are different from the atoms of all other elements

4

Compounds are composed of atoms of more than 1 element. The relative number of atoms of each element in a given compound is always the same.

5

Chemical reactions only involve the rearrangement of atoms. Atoms are not created or destroyed during chemical reactions.

Answer 2

Dalton’s Atomic Theory

The main points of Dalton’s atomic theory are:

1.Everything is composed of atoms, which are the indivisible building blocks of matter and cannot be destroyed.

2.All atoms of an element are identical.

3.The atoms of different elements vary in size and mass.

4.Compounds are produced through different whole-number combinations of atoms.

5.A chemical reaction results in the rearrangement of atoms in the reactant and product compounds.

Atomic theory has been revised over the years to incorporate the existence of atomic isotopes and the interconversion of mass and energy. In addition, the discovery of subatomic particles has shown that atoms can be divided into smaller parts. However, Dalton’s importance in the development of modern atomic theory has been recognized by the designation of the atomic mass unit as a Dalton.
