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

Average weight of an element expressed in atomic mass units?
Average weight of an element expressed in Atomic Mass units.
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)
What is atomic mass an average of?
"Atomic Mass" is not an average, it is tje total mass of all the electrons, protons and neutrons in an atom of an element. AVERAGE Atomic Mass is the AVERAGE of the Atomic Masses of all of the Isotopes of an element according to their natural proportions.
Average atomic mass of an element?
"The average atomic weight (not mass) of a chemical element is calculated considering the percentage of each natural isotope and the atomic masses of these isotopes."
What is the difference between average atomic mass and atomic mass?
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
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.
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.
Average weight of an element expressed in atomic mass units?
Average weight of an element expressed in Atomic Mass units.
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)
Which is the average of the mass numbers of an element's isotopes?
the Atomic Mass
What is atomic mass an average of?
"Atomic Mass" is not an average, it is tje total mass of all the electrons, protons and neutrons in an atom of an element. AVERAGE Atomic Mass is the AVERAGE of the Atomic Masses of all of the Isotopes of an element according to their natural proportions.
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.
What is the weighted average of the atomic masses of an element's naturally occurring isotopes is called the?
The atomic weight that is listed on the periodic table for each element is the weighted average of the atomic masses of an element's naturally occurring isotopes. So you are describing atomic weight as it is used on the periodic table.
