because an atomic number is the same as the number of electrons in an atom (not ion)
the Atomic Mass number is the number of protons/electrons in an atom
atomic number = number of protons = number of electrons atomic mass = mass of protons + mass of neutrons
To calculate the number of protons in an atom, use the atomic number (Z), which represents the number of protons. The number of neutrons can be calculated by subtracting the atomic number from the mass number (A = Z + N). Electrons are the same as the number of protons in a neutral atom.
17 electrons - atomic mass 35.5 and atomic number 17
atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number

Number of protons plus the number of neutrons (electrons don't matter as they have such a small mass).
17 electrons - atomic mass 35.5 and atomic number 17
The atomic number must be known along with the mass number. Then the number of protons or electrons is the same as the atomic number, and the number of neutrons is the difference between the mass number and the atomic number.
you can find electrons by subtract the atomic number and atomic mass.

The Atomic Mass is equal to the number of protons and electrons that an element has.
The charge of an ion can be calculated by adding up the protons and subtracting the electrons. When oxygen with 8 protons has 8 electrons it is neutral, when it has 7 electrons it is positively charged.
