How many isotopes of elements x exist?
Different elements have between 0 and 10 naturally occurring isotopes, and between about 3 and 25 if you also include artificially prepared and characterized ones.
When the masses of naturally occurring isotopes of a particular element are averaged the result is called the elements of what?
When the masses of naturally occurring isotopes of an element are averaged, the result is called the element's average atomic mass.
What are all the elements that do not have isotopes?
There are many elements that have only one naturally occurring isotope. When you get to transuranic elements the elements all have no naturally occurring isotopes. But all elements have isotopes, they just have to be created, maybe in a nuclear reactor or particle accelerator or a supernova explosion.
How many different elements occur naturally con earth?
There are 118 known elements on the periodic table, of which 92 occur naturally on Earth. These naturally occurring elements range from hydrogen, the lightest, to uranium, the heaviest. Some elements, like technetium and promethium, are radioactive and do not have stable isotopes, making them rare in nature.
How many naturally occurring atoms exist?
There are 92 naturally occurring elements, with a total of 118 naturally occurring elements in the periodic table. Each element is composed of atoms with a specific number of protons in the nucleus that determines its identity.
What is the weighted-average mass of all the known isotopes for an element?
The known weighted-averagemass of all the naturally occurring* isotopes for an element is the atomic mass of the element.____________________*This is not the same as "all the known isotopes", becausemost elements have known isotopes that are not naturally occurring.
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

Why are most elements radioactive?
Most of the natural occurring (isotopes of) elements are NOT radioactive.Though most of all the known isotopes are radioactive but most of them do NOT naturally occur.
How are artificially produced isotopes different from naturally occurring isotopes in terms of their properties and applications?
Artificially produced isotopes are different from naturally occurring isotopes in that they are created in a laboratory setting rather than being found in nature. These artificially produced isotopes often have different properties, such as stability and half-life, compared to naturally occurring isotopes. Additionally, artificially produced isotopes have various applications in fields such as medicine, industry, and research, where they can be used for purposes such as medical imaging, cancer treatment, and scientific studies.
How has the amount of earths radioactive isotope changed over time?
Many elements have naturally occurring isotopes, varieties of the element that have different numbers of neutrons in the nucleus.
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.
