Isotopes are identified by their mass numbers.
Isotopes are different forms of the same element which have different numbers of neutrons in their atomic nuclei. A given element is identified by the number of protons in its nucleus; that's its atomic number. Two different isotopes of the same element have the same number of protons, but each has a different number of neutrons in its nucleus. Different isotopes of the same element are chemically the same.
Isotopes. They differ in the number of neutrons in the nucleus.
Every individual atom is an isotope - it has a whole number of neutrons and a whole number of protons in its nucleus. The word isotope generally refers to a quantity of some material, where every atom in that portion has the same whole numbers as described above.
Atoms of the same element that differ in the number of neutrons they contain are know as isotopes. Isotopes are identified by their mass number. For example hydrogen with an extra neutron is called Deuterium.
Isotopes are identified by their mass numbers.
Radioisotopes are identified by the halflife, type of radiations emitted, energy of these radiations, spectrometry (mass, gamma, alpha), etc.

Einsteinium was identified for the first time in nuclear tests debris from Eniwetak by Albert Ghiorso and co-workers in 1952; after this isotopes of Es were prepared in laboratory.

Both isotopes and radioactive isotopes are pretty much the same but radioactive isotopes are better because it can be used to make medicine.
I believe 24 isotopes have been identified with atomic mass ranging from 32 to 55. Only three occur naturally, K39 (93% of the total), K41 (7%) and the radioactive K40 (0.01%). The others have very short half-lives, as small as a few nano-seconds in some cases.
The answer for isotopes is 259
