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.

John Dalton's atomic theory stated that atoms of the same?

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 concluded that all the atoms of a single what have the same mass?

He concluded that all atoms of an element have same mass and identical chemical and physical properties.


Who said atoms are made of single material formed into different shapes and sizes?

This theory was proposed by the ancient Greek philosopher Democritus. He postulated that all matter is composed of indivisible particles called "atoms" that vary in size and shape to create different substances.


When Dalton's theory is it possible to convert atoms of the one element into atoms of another?

No, according to Dalton's theory, atoms of one element cannot be converted into atoms of another. Atoms are indivisible and cannot be created or destroyed in a chemical reaction. This concept is known as the conservation of matter.


Dalton's atomic theory stated that every element was made of atoms that could not be subdivided atoms of the same element are like and?

Dalton's atomic theory states that elements are composed of indivisible atoms and that all atoms of a given element are identical in mass and properties. Atoms of different elements have different masses and properties.


Did Dalton say that all atoms are the same size?

No, Dalton did not say that all atoms are the same size. Instead, Dalton proposed that all elements are composed of indivisible particles called atoms, and that atoms of different elements have different sizes and properties.


Are atoms of the same element are identical part of Dalton's atomic theory?

Yes, according to Dalton's atomic theory, atoms of the same element are identical in mass and properties. This principle implies that all atoms of a given element are uniform and can be distinguished from atoms of other elements. Dalton's theory laid the foundation for understanding the composition of matter, although later discoveries revealed that isotopes of an element can exist with different masses.


What year did Dalton say that Atoms of the same element exactly alike?

John Dalton postulated that atoms of the same element are exactly alike in his atomic theory developed in the early 19th century.


What single measurable characteristic of atoms did Dalton base his conclusions on?

John Dalton based his conclusions on the measurable characteristic of atomic mass. He proposed that each element consists of unique atoms with specific masses, which could be used to distinguish one element from another. Dalton's atomic theory was grounded in the idea that chemical reactions involve the rearrangement of these distinct atoms, with their mass being a key factor in understanding chemical compounds and reactions.


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.


According to Dalton how do the atoms from one sample of the element carbon compare to the atoms of another sample of carbon?

They 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.
