The number of electrons is always the same as the atomic number. That gives you the number of protons and electrons. The atomic mass has nothing to do with it. What is the atomic number? That is your answer.
An atomic nucleus contain protons and neutrons; protons and neutrons contain quarks and gluons.
The number of protons in the nucleus of an atom determines an element's atomic number. In other words, each element has a unique number that identifies how many protons are in one atom of that element. For example, all hydrogen atoms, and only hydrogen atoms, contain one proton and have an atomic number of 1. All carbon atoms, and only carbon atoms, contain six protons and have an atomic number of 6. Oxygen atoms contain 8 protons and have an atomic number of 8. The atomic number of an element never changes, meaning that the number of protons in the nucleus of every atom in an element is always the same.
The atomic number of an element depends on the number of protons in that element.

it has 9 electrons atomic number= number of protrons and electrons and atomic mass-atomic number=neutrons

Protons = Atomic Number = 50 Neutrons = Atomic Mass - Atomic Number = 125 - 50 = 75

This would contain 50 protons.
The four pieces of information in each box of most periodic tables are the element's name, the element's symbol, the element's average atomic weight and the element's atomic number. Other periodic tables have other information, but standard periodic tables almost always have those four.
All atoms of oxygen contain 8 protons. It doesn't matter which isotope you have.

Atomic number = number of protons in an atom, and = number of electrons in an atom.
