Not necessarily, because most elements have isotopes, which have slightly different weights. However, atoms of a particular element always have the same number of protons, equal to the atomic number of the element.
Yes. We now know that that is incorrect. Isotopes are atoms of a given element with different mass numbers. This is an example of how a theory can be changed when new evidence supports a different conclusion. The theory isn't totally thrown out, just changed to accommodate the new data.
John Dalton concluded that all the atoms of a single element have the same mass. This has been proven false as they all have different masses.
Dalton in his atomic theory mentioned that all the atoms of an element are identical and have similar physical and chemical properties.
atoms are real eventought they are invisible
All atoms do not have the same mass, but atoms of the same element generally do have the same mass.

The Dalton theory is not applicable to nuclear reactions.
Atoms are divisible.
John Dalton
John Dalton was the adept of the atomic theory and a prominent founder.The five main points of John Dalton's atomic theory: · Elements are made of tiny particles called atoms. · All atoms of a given element are identical. · The atoms of a given element are different from those of any other element.
According to John Dalton, all the atoms of a single element will have the same mass. This is the basis for the modern atomic theory.

John Dalton it was referred to the atoms of the same element.
He concluded that all atoms of an element have same mass and identical chemical and physical properties.
The Dalton theory is not applicable to nuclear reactions.
atoms are made of protons, neutrons, and electrons.
Because the existence of isotopes was discovered not all atoms of an element are identical.

Atoms are divisible.
Atoms are indivisible and indestructible, and all of the atoms of a given element are identical in mass.
They are identical.
