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.
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 atomis mass
For the chemical elements the correct expression is atomic weight.This value is the weighted average mass of the natural isotopes of this element.
The atomic mass of an element is the weighted average of masses of the isotopes of the element, weighted in proportion to their abundance.
it is the weighted average of the masses of an element's isotopes.
it is the weighted average of the masses of an element's isotopes.
it is the weighted average of the masses of an element's isotopes.
The weighted average of all of the natural occuring isotopes for a particular element is called its Atomic Weight (or Relative Atomic Mass)
The weighted average of all of the natural occuring isotopes for a particular element is called its Atomic Weight (or Relative Atomic Mass)
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 isotopes (that is a weighted average). You have to take into account the abundance of each isotope when they do your averaging.
