Neutrons can be removed or added to change the atomic mass of an atom; a atom with the same amount of protons but different amounts of neutrons are called isotopes.(Taking or removing protons would change the type of atom and electrons do not have sufficient mass to change the atomic mass.)
Since the atomic mass consists of protons and neutrons, adding a proton would add one unit to the atomic massguessing that the number of neutrons doesn't change.
We make atomic number by number of protons in a atom. We make mass number by total of both protons and neutrons.
The number of neutrons has no influence on the number of the atomic number. Only protons do, and they only change in nuclear chemistry.

The number protons in an atom is called the atomic number (it is this number that tells us which element the atom is). The number of neutrons in an atom can change, but the term for the amount of neutrons is called an isotope. The number of protons and neutrons added together is called the atomic mass.
the number of protons change because of the more protons you add on
you can find the number of protons by looking at the atomic number (53), as the number of protons does not change between isotopes. You can find the number of neutrons by subtracting the atomic number from the Atomic Mass (131), therefore, iodine-131 has 53 protons and 78 neutrons.

the nucleus is made of protons and neutrons together. the protons have a positive charge and the neutrons have no charge [electrons circle the nucleus and have a negative charge]

Atomic numbers are determined by the number of protons an atom has. The mass number is determined by the number of protons and neutrons. While the number of protons can't change (as the element itself would change), neutrons can and do vary. These are called isotopes.
The number of protons in Chlorine is relative to its atomic number of 17. The amount of protons will not change, or will become a different element. The 37 refers to the amount of nucleons in the element. The total nucleons is calculated by adding the amount of protons and neutrons, so if we know there are 17 protons, 37-17= 20 neutrons. There are 17 protons and 20 neutrons in Cl-37.

because it becomes more complex and the nuclei has to mange more neutrons Sources: Science Teacher
The different isotopes have different Atomic Mass numbers, because the isotope has different numbers of neutrons. The protons and electrons are the same, so the change in mass number is the same as the change in the number of neutrons.
