Why is it important to use a weighted average when determining the average atomic mass of your element?
The majority of chemical elements have one or more natural isotopes; each isotope has a different mass and concentration. A weighted average atomic weight is unavoidable for a correct evaluation.
Don't use the expression atomic maas - this in only for isotopes. For chemical elements IUPAC recommend atomic weight.

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?
The atomic mass of an element is the average mass of an element's isotopes, weighted by their natural abundance. It is expressed in atomic mass units (u) and is often close to the mass number of the most abundant isotope of the element.
What is the average atomic mass compared to atomic mass?
The average atomic mass is a weighted average of the masses of all isotopes of an element, taking into account their abundance. The atomic mass listed on the periodic table is the weighted average of all naturally occurring isotopes of the element. So, they are essentially the same thing, with the average atomic mass being a more specific term.
How the atomic mass of an element is affected by the distribution of its isotopes in nature?
The atomic mass of an element is the average of its isotopes, weighted by abundance in nature.
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 weighted average mass of an element isotopes?

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.
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.
Which best describes the definition for the atomic mass of an element?
The atomic mass of an element is the average mass of an element's isotopes, weighted by their natural abundance. It is expressed in atomic mass units (u) and is often close to the mass number of the most abundant isotope of the element.
What is the weighted average of the atomic masses of an element's naturally occurring isotopes is called the?
The weighted average of the atomic masses of an element's naturally occurring isotopes is called the atomic mass. This value takes into account the abundance of each isotope in nature when calculating the overall average atomic mass of the element.
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 weighted average of the masses of all naturally occurring isotopes of an element?
The atomic weight of the element (syn.: mass number).
The average atomic mass of an element is the average of the atomic masses of its?
The average atomic mass of an element is the average of the atomic masses of its isotopes (that is a weighted average). You have to take into account the abundance of each isotope when they do your averaging.
What is the average atomic mass compared to atomic mass?
The average atomic mass is a weighted average of the masses of all isotopes of an element, taking into account their abundance. The atomic mass listed on the periodic table is the weighted average of all naturally occurring isotopes of the element. So, they are essentially the same thing, with the average atomic mass being a more specific term.
What is a weighted average of the masses of all of the naturally occurring isotopes of an element?
The mean Atomic Mass.
How do you calculate the atomic mass of an element containing a mixtures of isotopes?
