They are not directly equatable terms.
Strictly, every atom from from one isotope of the relevant element - some elements having few stable isotopes, others having a number and most having at least one unstable (i.e. radioactive) isotope.
That is a hard answer to find. However if you consider that the Atomic weights on the Periodic Table is the average of all the isotopes and their comparative abundance, then I would say they all have isotopes. This is because none of the weights are integers without decimals. This proves that at least one other isotope exists. Except for the ones in ( ), which are non decimal but I checked; they all have isotopes, or should have isotopes that have not been discovered because of their rarity or instability. That is the reason for the ( ).
The question as asked is a bit strange. All atoms are isotopes of some element, and all elements have at least one isotope. However, an element is not and cannot be an isotope, by definition. It's sort of like asking if most cars are wheels... a car has wheels, but it isn't a wheel itself.
No - only hydrogen lacks neutrons. It has 1 proton and 1 electron.
All elements have isotopes. However, other elements like Xenon have as much as 7 stable isotopes while others like Technetium, have no stable isotopes at all.
no, some have more than one
no,not all
Isotopes are just the different possible nuclear weights of each element. Some are stable; some are unstable and radioactive. Since all atoms are isotopes and all isotopes are atoms, Isotopes can - and do - form ions, consequently they can have positive and negative charges.
All atoms of an element contain the same number of electrons and protons but they can have different numbers of neutrons. Atoms with different numbers of neutrons are isotopes.
Uranium has a number of isotopes including U235 and U238, both of which are radioactive
Like almost all of the other elements bromine is a mixture of so-called isotopes. All of these isotopes are bromine and have almost identical chemical properties. They all have the same number of protons in the nuclei of their atoms. However, the numbers of neutrons in their nuclei vary. The atoms of some isotopes of bromine are a little heavier than the atoms of other isotopes. The atomic weight of bromine is the average weight of all of the isotopes of bromine, so it cannot be a whole number.
No, atoms of the same element have the same number of protons. Atoms of the same element with different numbers of neutrons are called isotopes.

Isotopes are atoms of the same element with varying number of neutrons. Thus, not all atoms are the same.
# Elements are not isotopes, atoms are isotopes of an element. # There are no atoms that are not isotopes, so it's not a matter of being "considered" an isotope or not. # It doesn't matter where the neutrons come from, whatever that means. All atoms are isotopes of some element or other.

This question is misguided. Atoms do not have isotopes. In a sample of an element there are many atoms. They will all have the same number of protons in their nuclei, that's what makes them the same element. Individual atoms may have different numbers of neutrons, if this happens they are called isotopes. For instance in silver, all the atoms have 47 protons, but some of them have 60 neutrons and some have 62. We say that silver has two stable isotopes. Perhaps your question should be 'Do all atoms of the same element have the same number of neutrons?'
All gold atoms (excepting artificial isotopes) are similar.
Because the existence of isotopes was discovered not all atoms of an element are identical.
A natural chemical element may be monoisotopic or has isotopes. Isotopes are atoms but they differ from other isotopes by the number of neutrons. This involve a different atomic mass and different physical properties or sometimes (for light isotopes) different chemical properties. Also, all chemical elements have radioactive, artificial isotopes.

In his time were not known the isotopes and Dalton supposed that all atoms of a chemical element are identical.
