Is there any relation between the total number of protons and neutrons in an atom and its mass?

1 mole of a diatomic element X_2 contains 34 and 40 moles of electrons and neutrons respectively. The isotopic formula of the element is:

True or false? . a) All particles in the atom have charge. b) Electron and proton haveopposite charges. So atom has no charge. c) Mass number is the total number of electron, proton and neutron. d) The number of neutrons are obtained on substracting atomic number from mass number.

Symbols of certain isotopes are given in table ,Complete the table writing their atomic number, mass number, number of protons, electrons and neutrons.
