Yes; isotopes of the same element have the same atomic number but differ in their atomic masses.
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
It isn't, as such. Isotopes of the same element have different numbers of neutrons, and neutrons have a mas of one atomic mass unit (amu). So isotopes have different atomic masses, but being told the number of neutrons any isotope has, will not enable you to say what element or atomic mass it had, unless you remembered the details for every single isotope. Even then different elements can have the same number of neutrons. Isotopes do get named after their atomic mass however - uranaium 235 has an atomic mass of 235, for instance.
The mass number for a particular isotope of an element is a precise value. The average atomic mass for an element is the value you would measure for that element given all the isotopes it has and their abundance in the sample.
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.

The number of neutrons in the nucleus is different in each isotope of an element. Isotopes of an element have the same number of protons (atomic number) but different numbers of neutrons, leading to variations in atomic mass.
The atomic mass number of oxygen is 16.0. --------- The mass number is the sum of neutrons and protons in the atomic nucleus and is different for each isotope of any element. For example the isotope oxygen-16 has the mass number 16. After IUPAC Tables from 2009 the atomic weight of oxygen is [15,99903; 15,99977]. The conventional (abridged) atomic weight is 15.999 amu.
The mass number is the sum of neutrons and protons in the atomic nucleus and is different for each isotope of any element. For example the isotope oxygen-16 has the mass number 16.
Yes, the atomic mass of an element takes into account the relative abundance of each isotope of that element. This is because atomic mass is the weighted average of the masses of all isotopes of an element based on their natural abundance.
