An isotope is an atom; a chemical element may be formed from one or more isotopes having the same number of protons and electrons but with different number of neutrons.
Elements with no stable isotopes are called radioactive elements. These elements spontaneously undergo radioactive decay, which leads to the formation of stable isotopes over time.
All of the isotopes in an element's atomic masses divided by the amount of isotopes there are is the weighted-average mass of the mixture of an elements isotopes.
No most of them are not isotopes. Few elements exist as isotopes.
element vs isotopes
Isotopes are atoms of the same elements with different number of neutrons.
Isotopes of elements are atoms with the same number of protons but different numbers of neutrons. This causes isotopes of the same element to have different atomic masses. Isotopes can be stable or unstable, with unstable isotopes undergoing radioactive decay.
Many elements have different isotopes: 1) Carbon - Carbon 12, Carbon 14 2) Hydrogen - Protium, Deuterium, Tritium 3) Chlorine - Chlorine 35, Chlorine 37 etc
Yes, synthetic elements and transition elements can produce isotopes. Synthetic elements, which are typically created in laboratories through nuclear reactions, often have unstable isotopes that decay over time. Transition elements, while many are stable, also have isotopes that can be either stable or radioactive, depending on the element and its nuclear configuration. The variety of isotopes in both categories can have applications in fields such as medicine, industry, and research.

Not all of the transition elements are radioactive. Many of them are, and some of them have common radioactive isotopes, but some of them have no naturally occurring radioactive isotopes. Please note that all elements have synthetic radioactive isotopes, at least.
No, some elements (Ac, Th, Pa, Rn, U, Th, etc.) and many other isotopes are natural elements or isotopes.
