What is the result when you total the individual percent abundance of isotopes of a given element?
How do you calculate percent abundance of an isotope?You find the isotope number and then you calculate that into a fraction and then turn the fraction into a percentage and divide it by the atomic number then times it by the mass and turn that answer into a percent and voila, there you have it.
What is the natural abundance of Ag-107 is 51.84 percent What is the natural abundance of Ag-109?
48.16%
What are silicon antimony and polonium?
All are natural chemical elements: silicon and antimony are metalloids, polonium is generally considered a metal.
If an element has three isotopes with known natural abundance percentages what other information is needed to find the average atomic mass of the element?
The abundance percentage of each isotope
What is the natural abundance for iodine-131?
it is made in stuff.
Explain what is meant by the natural abundance of isotopes?
If a substance is said to have a natural abundance of isotopes, it means the substance is found in large numbers in nature with an electric charge. Substances found in nature are usually electrically neutral.
What is natural abundance?
Natural abundance refers to the relative amount of different isotopes of an element that occur naturally in the environment. It is expressed as a percentage and reflects the distribution of isotopes based on their atomic masses. Natural abundance varies depending on the element and is important in various fields such as chemistry, geology, and environmental science.
What is the formula to find the natural abundance?
In chemistry, natural abundance refers to the abundance of isotopes of a chemical element that is naturally found on a planet. Its formula is given as: abundance of isotope = average atomic weight of the element / exact weight of isotope.
Are regular isotopes originaly stable?
Some natural isotopes are stable or have half-lives greater than the age of the Universe. But other natural isotopes are radioactive and have finite half-lives. It all depends on the particular isotope.
Which of isotopes of bromine exist in greater numbers?
Two natural isotopes of bromine are known:- bromine-79: 50,69 %- bromine-81: 49,31 %
What are the natural abundance in percent of sodium's 3 most common isotopes?
Sodium is considered a monoisotopic chemical element - sodium-23; the isotopes sodium-22 and sodium-24 exist only in ultrtraces.
Why do elements which exists as isotopes have fractional atomic mass?
Each isotope of an element has a different Atomic Mass, so an average is taken of all the isotopes, but the average is weighted because the natural abundance (%) of each isotope is factored in. If hydrogen-1 is much more abundant than deuterium and tritium, then the weighted average will be closer to 1 than 2 or 3 but not a whole number. The following equation shows how percent abundance factors into the weighted average. (atomic mass A)(X% abundance) + (atomic mass B)(Y% abundance)...=(weighted average of all isotopes of the element)(100% abundance)

What is the natural abundance of 63cu?
The natural abundance of 63Cu is about 69.17%.
Is natural isotopes and natural radioactive isotopes are same?
yes
