According to Dalton, atoms combine in ____ to form compounds
Answers
Answer:
According to Dalton, atoms combine in a fixed ratio to form compounds. To form a water molecule (H2O), always 2 hydrogen atoms and one oxygen atom combine together.

Explanation:
According to Dalton , atoms combine in fixed ratio to form compounds .
Extra information :-
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.
Terms
atomic mass unitThe standard unit that is used for indicating mass of an atom.
atomThe smallest possible amount of matter that still retains its identity as a chemical element, now known to consist of a nucleus surrounded by electrons.
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.
