Question

when the electrons are successively filled in the orbitals of same shell orbital which is filled at the end requires less energy to remove the electron justify​

Answer 1

Answer:

Notice that the 2s orbital has a slightly lower energy than the 2p orbitals. That means that the 2s orbital will fill with electrons before the 2p orbitals. ... This is because the p orbitals all have the same energy and the electrons prefer to be on their own if that's the case.
