Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of hassium is 108; each isotope of an element has a different number of neutrons and a different atomic mass.
average atomic massof an element=(Atomic mass of first isotope X % of that isotope) + (Atomic mass of second isotope X % of the second isotope)
The two main factors in determining the average atomic mass of an element are:the isotopic composition of the element (the fraction of each isotope)the atomic mass of each isotope
Calculation of the atomic weight of an element having many isotopes:ia - atomic mass of the isotope a x percent concentration of the isotope in the elementib - atomic mass of the isotope b x percent concentration of the isotope in the elementic - atomic mass of the isotope c x percent concentration of the isotope in the element...........................................................................................................................iz - mass of the isotope z x percent concentration of the isotope in the elementMake the sum: I = ia + ib + ic + ..... izThe atomic weight of the element is: I/100 (the term weight is recommended by IUPAC in this case).
Isotopes are determined by the number of neutrons in an atom's nucleus. Each isotope of an element has the same number of protons in its nucleus but a different number of neutrons. Isotopes of an element have the same chemical properties but different atomic masses.

isotope
It is an isotope of the element.
Because each isotope of an element has a mass different from any other isotope of the same element, and the atomic mass of an element is an average, weighted by the proportion of each isotope, in the naturally occurring element.
Each isotope of an element has a different number of neutrons: Atomic mass of the isotope - Atomic number = Number of neutrons
an isotope
average atomic massof an element=(Atomic mass of first isotope X % of that isotope) + (Atomic mass of second isotope X % of the second isotope)
The atomic number of an isotope is always identical to every other isotope, otherwise, it would form a separate element.

An isotope shares the atomic number with its element atom. How does it differ from the element atom?
