Are electrolytes isotopes?

Electrolytes are substances able to be dissociated in solution or after melting.Isotopes are atoms of chemical elements; isotopes have different number of neutrons.


What are two substances on the periodic table that are not an element compound or mixture?

Two substances on the periodic table that are not elements, compounds, or mixtures are isotopes and allotropes. Isotopes are atoms of the same element with different numbers of neutrons, while allotropes are different forms of the same element in the same physical state.


What is the slow breakdown of radioactive substances into more stable elements?

Radioactive elements break down in to stable isotopes through nuclear decay. The list of isotopes from a nuclear isotope to a stable isotope is called its decay chain.


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.


What does a radiochemist study?

A radiochemist studies the chemical properties and behavior of radioactive substances, including how they interact with other elements and molecules. They may investigate the production, detection, and applications of radioactive isotopes in fields such as medicine, environmental science, and nuclear energy.


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?

element vs isotopes


Is an element a new substance or does it even change state?

I'll try to answer what I think you were trying to ask.Different elements are different substances. Technically, different isotopes are different substances as well, but in practice the chemical differences between two isotopes of the same material are much smaller than the differences between two different elements.All elements (and nearly all compounds) undergo state changes.


When are substances isotopes?

Isotopes are atoms of the same element but having a different number of neutrons.


Are isotopes nonmetal metal metalloid?

Metals, metalloids, and nonmetals all have isotopes. It depends on which element as to whether it is a metal, a metalloid, or a nonmetal, not whether it is an isotope.


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

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