Question

Explains why the ionization energy goes through a minimum between Nitrogen and Oxygen. (2)


A.

Nitrogen also has the added stability of a half-filled shell of electrons in the 2s subshell, while in oxygen of the 2s orbital has a pair of electrons. This invokes electron-electron repulsions, thus increasing the amount of energy required to remove an electron.
B.

Nitrogen also has the added stability of a half-filled shell of electrons in the 2p subshell, while in oxygen one of the 2p orbitals has a pair of electrons. This invokes electron-electron attractions, thus lowering the amount of energy required to remove an electron.
C.

Oxygen also has the added stability of a half-filled shell of electrons in the 2p subshell, while in nitrogen one of the 2p orbitals has a pair of electrons. This invokes electron-electron repulsions, thus lowering the amount of energy required to remove an electron.
D.

Nitrogen also has the added stability of a half-filled shell of electrons in the 2p subshell, while in oxygen one of the 2p orbitals has a pair of electrons. This invokes electron-electron repulsions, thus lowering the amount of energy required to remove an electron.
E.

Nitrogen also has the added stability of a completely-filled shell of electrons in the 2p subshell, while in oxygen one of the 2p orbitals has a pair of electrons. This invokes proton-proton repulsions, thus lowering the amount of energy required to remove an electron.
