Relative abundance of Copper-63 is 69.17% and Copper-65 is 30.83%
The atomic mass listed on most periodic tables is actually the average atomic mass representing the average atomic masses of the various isotopes of an element depending on their percent natural abundance. Refer to the answers.com question: What is the formula for finding average atomic mass? for a detailed explanation on how to calculate this value. (What_is_the_formula_for_finding_average_atomic_mass)
The atomic number is the amount of protons which will equal the amount of electrons. The average atomic mass minus the number of protons will equal the amount of neutrons.
The masses and relative abundances of all naturally occurring isotopes of the element are required to calculate average atomic mass of the element.
The atomic mass unit (amu) is a unit of mass used to express the average mass of an atom or molecule. To calculate the atomic mass unit of gold (Au), you would look at the atomic mass of gold on the periodic table, which is approximately 197 amu.
To calculate the median atomic weight, the relative abundance of each isotope could be calculated or given.

the atomic number of each isotope-apex;)
There is no average atomic number. The atomic number of an element is the number of protons in the nuclei of its atoms. It is a whole and finite number. The elements are arranged in order of increasing atomic number on the periodic table.
The atomic number is the amount of protons which will equal the amount of electrons. The average atomic mass minus the number of protons will equal the amount of neutrons.
weighted average of the various iisotopes

Atomic mass of = 34.9689 amu Atomic mass of = 36.9659 amu % of = 75.77 % of = 24.23 Average atomic mass = amu Found this answer on examville.com
The same way you calculate the atomic mass of other elements.
Atomic mass - Atomic number
Usually, the weight of an atom would be about twice that of the atomic number. For example, Boron's atomic number is 5, and it has an atomic mass 0f 10.81 amu. This is because of the fact that a neutron and a proton both weight about 1 amu, and an electron is insignificant. To calculate the atomic weight to a higher accuracy than a mere estimate, is beyond me. I hope this helped.
