1.	The Aufbau principle states that…….? * a) Only two electrons can occupy an orbitalb) Electrons enter the lowest available energy levelc) Electrons remain unpaired if possibled) Orbitals are regions in space where one is likely to find an electron
Answer» b)Explanation:The Aufbau principle states that the electrons occupy the lowest available ENERGY levels. And the orbitals are ARRANGED in increasing order of their energy as 1S 2s 2p 3s 3p 4S 3d . . .
