Many atoms exist in the form of different isotopes. These have different numbers of neutrons and so their atomic masses are different. The Atomic Mass for the element is the average of these masses, weighted together according to their abundance.

Why do some elements not have relative atomic masses eg. radium?
All the elements has an atomic weight; sometimes for the unstable radioactive elements is indicated only the value of the atomic mass of the most stable isotope.The term atomic weight is used for elements and the term atomic mass for isotopes (after the rules and the tradition of IUPAC).
Which value is used to arrange the elements in the periodic table?
atomic weight
What is the value that depends on the distribution of the elements isotopes in nature and the masses of those isotopes?
This value is the atomic weight.
What does Increase Decimal mean in Excel?
It mean to add more decimal places to a value. Sometimes this will show a more accurate value, rather than a rounded up value which is being shown because there are not enough decimal places to show the value in full.
The atomic mass of the elements are not whole value numbers because of the existence of?
D. Protons
What element has an atomic mass of 12?
The element that has the atomic mass of 12 is carbon. For elements the correct expression is atomic weight (not mass). The atomic weight of carbon (after IUPAC 2009) is [12,0096; 12,0116] or as a more simple, conventional value 12,011.
What was Dmitri Mendeleev able to do show the value of his contribution?
he created the first periodic table tat organized elements by their atomic number.
The atomic mass of an element is defined as the weighted average mass of that element's?
For the chemical elements the correct expression is atomic weight.This value is the weighted average mass of the natural isotopes of this element.
What is the value of a number after a decimal?
the place value after a decimal point is tenths
What is the decimal place value for 0.0658?

What is the decimal value of 115.9 percent?
decimal value of 115.9 percent is 1.159.
What would 1.3 value of a decimal be?
It would be the value of the decimal increased by 30%.
