If you think to the number of protons in an element atom this number is equal to atomic number of this element.

The calculation of the mass of the proton and other properties are another questions and problems.

There is not much calculating to do. Simply see what element it is and look it up on the Periodic Table. The atomic number is the number of protons.

How do you calculate the atomic mas based on the number of protons and neutrons of an atom?

Atomic mass is simply the sum of the number of protons and the number of neutrons. If an atom has "A" protons and "B" neutrons, its atomic mass is A + B.
