Table of relative atomic mass
WebFor example, the difference of atomic mass between element A and B =2.5u, difference between element B and C =3u, difference between element C and D =1u, Considering these cases, the elements do not have periodic increase in atomic mass . Therefore, we cannot predict element can come between these elements.. WebThe mass of an element shown in a periodic table or listed in a table of atomic masses is a weighted, average mass of all the isotopes present in a naturally occurring sample of that …

WebIn fact, subsequent work has shown that in a periodic table, elements should not be ordered strictly by atomic mass. For example, tellurium comes before iodine in the periodic table, even though its atomic mass is slightly greater. Such anomalies are due to the relative abundance of the "isotopes" or varieties of each element.
