Which of the following properties can only be a whole number?

Bohr's atomic model can explain the spectrum of:

If the energy of the second Bohr's orbit in H-atom is $$- 328 \ kJ$$ $$mol^{-1}$$, then what is the energy of the fourth Bohr orbit?

When 3d orbital is completely filled, the next electron will enter the :

In 'Aufbau principle', the term Aufbau represents :

When 3d orbital is complete, the next entering electron goes into :

The electron should be filled in the orbital in accordance with the increasing order of their energy. This statement is related with :
