Answer:
Explanation:
Dalton’s Atomic Theory
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: His theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements were had atoms of differing size and mass.
Explanation: his bibliography is as follows : Chemist John Dalton was born September 6, 1766, in Eaglesfield, England. ... In 1803 he revealed the concept of Dalton's Law of Partial Pressures. Also in the 1800s, he was the first scientist to explain the behavior of atoms in terms of the measurement of weight. Dalton died July 26, 1844 in Manchester, England.
