Answer:
Dalton’s atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements had atoms of differing size and mass.
Dalton’s atomic theory also stated that all compounds were composed of combinations of these atoms in defined ratios.
Dalton also postulated that chemical reactions resulted in the rearrangement of the reacting atoms.
Explanation:
The main points of Dalton’s atomic theory are:
Everything is composed of atoms, which are the indivisible building blocks of matter and cannot be destroyed.
All atoms of an element are identical.
The atoms of different elements vary in size and mass.
Compounds are produced through different whole-number combinations of atoms.
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.
Answer:
Dalton's atomic theory
For about 2000 years, the atomic theory remained a mere speculation. It was John Dalton, an English school teacher, who proposed his atomic theory in 1808, based upon inferences drawn from experimental observations. This theory is known as Dalton's atomic theory.
The main points of his theory are:
All matter is made up of small indivisible particles called atoms. Atoms cannot be created, destroyed or subdivided.
The atoms of an element are identical in all respects, but the atoms of one element
are different from the atoms of any other element, The atoms of an element combine in a small whole number ratio to form molecules of the elements. .
The atoms of one element combine with atoms of another element in a small whole
number ratio to form molecules of compounds.
In a chemical reaction, atoms are combined, separated or rearranged.
