These values of the atomic masses can be explained by the effect of the relative abundances of the isotopes of the elements contributing to produce the observed net mass. If an element consists of n1 atoms of isotope 1, n2 atoms of isotope 2, etc., the atomic fraction x1 for isotope 1 ...

What is the atomic mass of an element?Elements:There are currently 118 identified electrons organized according to increasing atomic number from hydrogen (#1) to oganesson (#118). Each element has either a one-letter or two-letter abbreviation called its atomic symbol.Answer and Explanation: ...
atomic weight,relative atomic mass mass- the property of a body that causes it to have weight in a gravitational field combining weight,eq,equivalent weight,equivalent- the atomic weight of an element that has the same combining capacity as a given weight of another element; the standard is 8...
