How many naturally occurring isotopes are in technetium?
Technetium is a man made element.
How are isotopes different than naturally occurring elements?
Isotopes of an element have different masses because their nuclei have different numbers of neutrons.
When the masses of all naturally occurring isotopes of a particular element are averaged the result is call the elements?
Yes!
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.
The atomic mass of an element is defined as the weighted average mass of that element's?
For the chemical elements the correct expression is atomic weight.This value is the weighted average mass of the natural isotopes of this element.
What is the lightest artificial element?
The lightest artificial isotope is hydrogen-3, also called "tritium". The lightest element that has no naturally occurring isotopes is technetium.
What is the average of all the naturally occurring isotopes of a particular element?
The average of all the naturally occurring isotopes of a particular element are an element's atomic Mass.
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.
The average mass of all the known isotopes of an element is what?
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.
Is the weight 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.
Is radon the element naturally occurring?
The radon isotopes 222Rn and 220Rn are natural isotopes.
Is gallium a naturally occurring isotopes?
No. Gallium is an element. The element Gallium has two naturally occuring stable isotopes (69Ga and 71Ga) and abpout 29 unstable isotopes.
Is tin an isotope?
Tin is an element with ten naturally occurring isotopes.
How is the atomic mass of an element calculate?
By taking the wieghted averages of naturally occurring isotopes of that element. :)
How many naturally occurring isotopes are in technetium?
Technetium is a man made element.
Are the mass number is an average of the masses of all naturally occurring isotopes of an element?
Yes they do.
What is a weighted average of the masses of all of the naturally occurring isotopes of an element?
The mean Atomic Mass.
