This is a chemical element with a specific atomic weight.
The average of all the naturally occurring isotopes of a particular element are an element's atomic Mass.
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.
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.
This is the atomic weight.
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.
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.
The atomic mass that you see on the periodic table is an average mass taken from all of the element's known isotopes. Simply find the average of all of the masses of the 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.
Atomic mass is the average mass of all isotopes of a given element.
the average atomic mass is computed by summing all isotopic weights of the isotopes of that element and then dividing this by the the total number of isotopes of that element (note that isotopic mass is exactly the same as atomic weight, except for isotopes).
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.
"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.
