The given sodium atom with 11 protons, 11 neutrons & 11 electrons is Na-22
1) if this sodium atom gained a proton :-
The atomic number shall get increase by 1 & it will become Magnesium isotope of mass number 23.
i.e. Mg - 23
2) if this sodium atom gained a neutron :-
The mass number of sodium shall get increased by 1 & it will become isotope of sodium with mass number 23.
i.e. Na - 23
3) if this sodium atom gained an electron :-
It will become an anion of given sodium atom Na-22.
i.e. Na-

What is responsible for the mass defect when protons and neutrons combine to form a nucleus?...
What is responsible for the mass defect when protons and neutrons combine to form a nucleus? The mass defect comes from the electrons of the newly formed atom. The mass difference comes from an extra neutron or proton. The mass defect is due to our inability to measure the masses of subatomic particles accurately enough. The mass defect arises from mass being converted into nuclear binding energy.
