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.
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.
Isotopes of elements?
Uranium has a number of isotopes including U235 and U238, both of which are radioactive
What isotopes are atoms of the same elements with different number of?
Isotopes are atoms of the same elements with different number of neutrons.
Do all isotopes only occur in heavier elements?
No, isotopes of light elements exist as well. For example, there are several isotopes of the lightest element, hydrogen.No, even the lightest element (hydrogen (H)) has isotopes. These are called Deuterium and Tritium.All elements have isotopes but some of them are very unstable and have disappeared in nature over time.

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 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?
element vs isotopes
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.
Isotopes of elements?
Uranium has a number of isotopes including U235 and U238, both of which are radioactive
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
Pure substances that cannot be separated into simpler substances?
Element (It IS possible to alter elements by bombarding them with sub atomic particles and attempting to either augment or spilt the nucleus. Some elements are self-altering. These are the radioactive isotopes and they can change to several different elements before reaching their end state.)
