Which best describes the definition of the atomic mass of an element?
it is the weighted average of the masses of an element's isotopes.
Which best describes the definition for the atomic mass of an element?
it is the weighted average of the masses of an element's isotopes.
Why is it important to use a weighted average when determining the average atomic mass of your element?
It is important to use a weighted average because different isotopes of an element have different atomic masses due to the presence of different numbers of neutrons. The abundance of each isotope also varies, meaning some isotopes are more common than others. By using a weighted average, the more abundant isotopes have a greater contribution to the overall average atomic mass of the element, providing a more accurate representation.
What Is the weighted average of all of the isotopes of an element.?
The answer is the atomic weight of the original element: It's the number on the top left of each element square of the Periodic Table.
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)
How do the decimal places on the atomic masses of elements realate to isotopes?
The atomic mass of an element is the weighted average of masses of the isotopes of the element, weighted in proportion to their abundance.
An average of the masses of all the naturallly occurring isotopes of an element?
The weighted average for all isotopes that occur in nature for an element is its atomic weight listed on the Periodic Table of the elements.
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 is an average of the masses of all the isotopes that occur in nature For an element?
The weighted average for all isotopes that occur in nature for an element is its atomic weight listed on the Periodic Table of the elements.
Atomic mass used in a sentence?
The atomic mass of an element is the weighted average of the masses of all the stable isotopes of the element (if it has any), weighted by the natural occurrence levels of the isotopes in the elements as found on earth or in the atmosphere.
Why atomic mass of atom is defined as relative atomic mass?
It is calculated as the ratio of the mass of one atom of an element to one twelfth of the mass of an atom of carbon-12. In fact, the weighted average of the mass of an atom of an element - weighted according to its isotopic abundance.

What is weighted average mass of an element isotopes?
average atomis 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.
