No, all elements have so called isotopes, meaning that the number of neutrons in the nucleus differs from the most common isotope. Hydrogen, for example, has three known isotopes: 11H, 12H, 13H, where the first one is the most common. They solely in their number of neutrons, not protons. The last two isotopes are less stable, hence less common.

∙ 13y agoNo, not necessarily. All atoms of an ISOTOPE are identical. In some elements, the atoms have different number of neutrons. These atoms are called isotopes.

Are beryllium atoms identical?
Each atom of an isotope of beryllium (or of another element) is different from the atoms of an other isotope. But all the atoms of an isotope 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.
Which two of Dalton's theory were incorrect?
These affirmations are not valid today:· All atoms of a given element are identical.· A given compound always has the same relative numbers of types of atoms.
Who said that all atoms of an element are identical in size mass and other properties?
John Dalton
What best describes all atoms of a particular element?
They have the same number of protons
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.
The number of these must be the same for all atoms of an element?
The number of protons is identical in all atoms of an element.
What makes all atoms of an element the same?
atoms are of an element are the same becasue the are all made from identical particles. there is no way to distinguish one electron from another electron. the same is true for neutrons and protons. so by virtue of the fact that its constituents are identical, all atoms of the same element are identical.
Are beryllium atoms identical?
Each atom of an isotope of beryllium (or of another element) is different from the atoms of an other isotope. But all the atoms of an isotope 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.
Dalton hypothesized that atoms are indivisible and that all atoms of an element are identical. It is now known that .?
Atoms are divisible.
Is aluminium a mixture or a compound or an element Explain the question?
Aluminium is a chemical element because all atoms are identical.
Substance in which all atoms are alike?
A substance in which all atoms are identical is called an element.
A substance in which all of the building block particles are identical is called?
An element. The particules are atoms.
All Atoms Of An Element Are Exactly?
All atoms of the same element are not identical. The atoms of same element with different number of neutrons are called as isotopes. Although, the number of protons and electrons are same in every atom.
Which two of Dalton's theory were incorrect?
These affirmations are not valid today:· All atoms of a given element are identical.· A given compound always has the same relative numbers of types of atoms.
What is the substance made up of atoms?
The atoms of an element are all identical.
