there more than 1000 isotopes...but all these are represented by single element in the Periodic Table so thats why it is called isotope because iso mean "same" tope means"place" e.g hydrogen have 3 isotope but in periodic table only protium represents the remaining s
Fusionable isotopes refer to the larger isotopes that are usually relatively stable.
Isotopes are atoms of the same element but with a different number of neutrons.
"Type" is ambiguous in this context. Do you mean isotopes? Or do you mean states of matter? (Helium has some exotic states of matter.)Wikipedia states that there are 8 helium isotopes, to of them (3-He and 4-He) stable."Type" is ambiguous in this context. Do you mean isotopes?

A higher percentage of daughter isotopes present in a sample, the older the rock is.
Isotopes
If you mean oxygen: like most elements, it has both stable isotopes, and unstable (i.e., radioactive) isotopes. 16O, 17O and 18O are stable; the unstable (radioactive) isotopes include 15O and 14O.
if you mean isotopes then isotopes of the same element have a different number of neutrons in the nucleus so have a different atomic weight.
Iron is an element, and there is only one element called iron (Fe). There are no iron element(s), but if you mean isotopes, then some iron isotopes are stable, and some aren't. No known element is stable in of it's isotopes.

Isotopes. They differ in the number of neutrons in the nucleus.
isotopes just mean they have a different number of neutrons so if the..Mass number = # of protons + # of neutrons -they will have a different (greater) mass
