34.Why is energy of 2s orbital of hydrogen atom is greater than the 2s orbital of lithium atom ?

Q. Assertion :The first ionization energy of Be is greater than that B. Reason: 2p orbital is lower in energy than 2s.

Q. Assertion :The first IE of $Be$ is greater than that of $B$. Reason: $2p$-orbital is lower in energy than $2s$.

Q. Assertion :The first IE of Be is greater than that of B. Reason: 2p orbital is lower in energy than 2s.

Q. Statement I The first ionisation energy of Be is greater than that of B.
