Element does not exist so I have to ignore that part. Atomic mass as it appears on the Periodic Table is an average mass of gram (weight) per mole of atom (see avagadros number). Furthermore, it is average in the sense that it is weighted based on the percentage of a specific isotope existing (some contain more neutrons than others) with the actual weight of each isotope

What is the average atomic mass of an element is the average atomic masses of what kind of isotopes?
average atomic massof an element=(Atomic mass of first isotope X % of that isotope) + (Atomic mass of second isotope X % of the second isotope)
Average weight of an element expressed in atomic mass units?
The average weight of an element is expressed in atomic mass units (amu) and is calculated based on the relative atomic masses of the isotopes of that element weighted by their abundance in nature. This value can be found on the periodic table for each element. For example, the average atomic mass of carbon is 12.011 amu.
Which is a factor in determining the average atomic mass of an element?
The two main factors in determining the average atomic mass of an element are:the isotopic composition of the element (the fraction of each isotope)the atomic mass of each isotope
What element has an average atomic mass of about 12?
Carbon has an average atomic mass of about 12.
Average atomic mass of an element?
The average atomic mass of an element is the weighted average of the masses of its naturally occurring isotopes, taking into account their relative abundance. It is usually listed on the periodic table below the element's symbol.
What element has an average atomic mass nearest to 79?
Selenium
What element has average atomic mass nearest to 31?
phosphorus
What element has an average atomic mass nearest to 62?
a dead elephant
What elements has an average atomic mass nearest to 31?
It's is element
What is the hundredth element on the periodic table?
The hundredth element on the periodic table is fermium, with the symbol Fm and atomic number 100. It is a synthetic element that is radioactive and typically produced in nuclear reactors.
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 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.
What is the average atomic mass of an element is the average atomic masses of what kind of isotopes?
average atomic massof an element=(Atomic mass of first isotope X % of that isotope) + (Atomic mass of second isotope X % of the second isotope)
Average weight of an element expressed in atomic mass units?
The average weight of an element is expressed in atomic mass units (amu) and is calculated based on the relative atomic masses of the isotopes of that element weighted by their abundance in nature. This value can be found on the periodic table for each element. For example, the average atomic mass of carbon is 12.011 amu.
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.
Which is a factor in determining the average atomic mass of an element?
The two main factors in determining the average atomic mass of an element are:the isotopic composition of the element (the fraction of each isotope)the atomic mass of each isotope
Why is there an average atomic mass?
There is an average atomic mass because all atoms of the same element do not have the same amount of neutrons (isotopes), therefore variations in atomic mass exist. The average atomic mass of an element is the estimated average of all the atoms of the same element, given the average of different isotopes in a scientific sample.
