That would be 131-54=77. The atom would have 77 neutrons.

you really should say the isotope has a mass of 131 amu, which would mean the combination of protons and neutrons in the nucleus adds up to 131 (called the mass number). so if there are 77 protons that means there are 131 - 77 neutrons or 54

Atomic mass is the finished form of protons and neutrons. as such, the atomic mass hence would be 25+30=fifty 5. An atom has the comparable form of protons and electrons except that's an ion.
