What are elements with no stable isotopes called?

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.


What is the average mass of the mixture of an elements isotopes?

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.


Are most of the periodic table isotopes?

No most of them are not isotopes. Few elements exist as isotopes.


What are the differences between elements and isotopes?

What isotopes are atoms of the same elements with different number of?

Isotopes are atoms of the same elements with different number of neutrons.


Which elements have different isotopes?

Many elements have different isotopes: 1) Carbon - Carbon 12, Carbon 14 2) Hydrogen - Protium, Deuterium, Tritium 3) Chlorine - Chlorine 35, Chlorine 37 etc


Do synthetic elements and transition elements produced isotopes?

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.

Are all transition elements are radioactive?

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.


Are all radioative elements synthetic?

No, some elements (Ac, Th, Pa, Rn, U, Th, etc.) and many other isotopes are natural elements or isotopes.


Which is more the number of elements or the number of isotopes?

The number of elements is more than the number of isotopes. There are 118 known elements on the periodic table, while each element can have multiple isotopes with varying numbers of neutrons. The number of isotopes per element can range from a few to dozens, depending on the element.
