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 of each isotope-apex;)
them mass number of an element is the total amount of nuetrons and protons in the element , and the atomic number is the amount of protons ( and electrons) in the element simply subtract the atomic number from the mass number and you'll have the number of neutrons in the element hope this helped x
protons plus neutrons = atomic number
Number of neutrons = Atomic mass - Atomic number

you look at either the atomic number or the number of electrons. That's the number of protons.
The atomic weight or atomic mass.
The atomic mass number of an element is the sum of the number of protons and neutrons in its nucleus. To get the atomic mass number of 28.09, it typically corresponds to the average atomic mass of an element on the periodic table. For example, the element silicon has an average atomic mass of approximately 28.09, indicating that a silicon atom has an atomic mass number of around 28.
Number of protons
It is the number of positely charged nuclear particles ( protons ).
equal to number of protons
well you look at the periodic table of elements. the atomic number equals the number of protons. Then subtract the number of protons from the atomic mass (both protons and nuetrons have atomic mass units of 1 and electrons equal 0). That will give you the number of nuetrons.
