Dalton hypothesized that atoms are indivisible and that all atoms of an element are identical. It is now known that .?
These hypotheses are not valid today.
Dalton hypothesized that atoms are indivisible and that all atoms of an element are identical. It is now known that?
Because the existence of isotopes was discovered not all atoms of an element are identical.
What is wrong with John Dalton's atomic theory?
John Dalton thought that atoms were indivisible, that all matter is composed of tiny indivisible atoms, and he thought that atoms in a given element are identical.
Which of Dalton's atomic theory is not supported?
Atoms are indivisible and indestructible, and all of the atoms of a given element are identical in mass.
Was Dalton's hypothesis that atoms are indivisible and all atoms of an element are identical?
That was part of his atomic theory. We know now that that part of his atomic theory was incorrect.
What did dalton tell us about atoms?
-Dalton told us that the basic unit of matter is the atom. -compounds are formed when different atoms combine in fixed proportions -all atoms of a given element are identical -all element are composed of indivisible atoms
Which parts of Daltons theory were later found to be erroneous?
dalton was wrong about atoms being indivisible. atoms are divisible into several subatomic particles. dalton was wrong about all atoms of a given element having identical properties.
The model proposed by John Dalton was helpful in advancing your understanding of the atom What aspect of his model was actually incorrect?
Incorrect: Atoms are indivisible and indestructible; and all atoms of an element are identical in mass.
What did Dalton's atomic theory state?
elements are composed of indivisible atoms and all atoms of a given element are identical and atoms of different elements are different that is they have different and have different masses and compound are formed by the combination of atoms of different element
The fundamental particle of a chemical element according to Daltons theory is?
The atom. Considered by Dalton to be indivisible and indestructible.
The fundamental particle of a chemical element according to Daltons theory is the?
The atom. Considered by Dalton to be indivisible and indestructible.
Which concept in Dalton's theory been modified?
