No, isotopes of light elements exist as well. For example, there are several isotopes of the lightest element, hydrogen.
No, even the lightest element (hydrogen (H)) has isotopes. These are called Deuterium and Tritium.
All elements have isotopes but some of them are very unstable and have disappeared in nature over time.
No, even the lightest element, hydrogen, has three isotopes.
Elements with no stable isotopes include technetium (element 43) and promethium (element 61) and all elements heavier than lead (elements 83 and higher). Bismuth, element 83, is virtually stable with an extremely long half life of 1.9 x 1019 years.
heavier isotopes can be produces but their halflives are in the microsecond or shorter range.
In the periodic table only the chemical elements appear; but tables for isotopes also exist.
This is due to the fact that all elements have isotopes, meaning that there atomic weight is in fact much greater than stated in the periodic table. This means that the elements are only weighed by their compound and not including the isotopes.
All elements have unstable isotopes so the answer would be everywhere. However if you mean 'elements with only unstable isotopes' thennumber 43 Technetiumnumber 61 Promethiumeverything above 92
No - the lightest element Hydrogen has three known isotopes
No, Gold and several other elements have only one stable isotope, Promethium & Technetium as well as all elements heavier than Bismuth have no stable isotopes.
These elements are used only for nuclear physics research or as a raw material to obtain new heavier isotopes.

Atoms of all elements can have neutrons in them. Only the element hydrogen has an isotope whose atoms do not contain neutrons, but all other isotopes of hydrogen have neutrons in them. In the heavier elements the number of neutrons always exceeds the number of protons in the atom.

Radioactive Elements (38) These elements are radioactive. They either have no stable naturally occurring isotope, or else are entirely artificial (all artificial elements have no stable isotopes). by Andrew Moore
Heavier elements - mainly, elements with an atomic number after that of iron - will only fuse at very high temperatures, mainly in supernovae.
