Because all the atoms that make up an element have the same number of protons but sometimes differ in their number of neutrons, some of the atoms of the element will vary in mass. This results in the weighted average sometimes having fractions of an atomic mass unit. For example, fluorine...

For instance, Hydrogen is approximately 99% hydrogen with a mass number of 1 and 1% with a mass number of 2. The average mass is a weighted average. We weight the more prevalent isotope more heavily. In order to calculate the relative average atomic mass of an element we need to know ...
Relative and average atomic mass bothdescribe properties of an element related to its different isotopes. However, relative atomic mass is a standardized number that's assumed to be correct under most circumstances, while average atomic mass is only true for a specific sample. ...
The atomic mass of an element is a weighted average of each and every isotope of an element on the basis of their natural abundance. It becomes simple to calculate the atomic mass of an element following this methodology. Solved Example For You ...
The mass-excess prediction includes the term of the gross feature of a nuclear mass surface, the shell terms and a small correction term for odd-odd nuclei. Two functional forms for the shell terms were used. The first is the constant form, and the sencond is the linear form. In ...
The formula mass for this compound is computed by adding the average atomic masses of its constituent elements: When computing the formula mass of an ionic compound, the average masses of neutral sodium and chlorine atoms were used, rather than the masses for sodium cations and chloride anions....
for covalent compounds: by summing the average atomic masses of all the atoms in the compound’s formula. Keep in mind, however, that the formula for an ionic compound does not represent the composition of a discrete molecule, so it may not correctly be referred to as the “molecular mass...
