Question

The first ionization potential of the elements B, C, and N (atomic numbers 5, 6, and 7) steadily increases, but that of O is less than that of N. The best interpretation of the lowervalue for O is that:1. the ionization potential of N is a maximum and the values decrease steadily for the elements O, F, and Ne.2. there is more shielding of the nuclear charge in O than in B, C, or N.3. the electron removed from O is farther from the nucleus and therefore less tightly bound than that in N.4. the electron removed from O corresponds to a different value of the quantum number L than that of the electron removed from B, C,or N.5. the half-filled set of p orbitals in N makes it more difficult to remove an electron from N than from O.

Answer 1

The best interpretation of the lower value for O is that : The half-filled set of p orbitals in N makes it more difficult to remove an electron from N than from O

Step-by-step explanation:

The potential for ionized electrons is a measure of how quickly an atom is destroyed.

The capacity for ionization is increased around the table from left to right. The actual electronic N atom structure is 2
`s^(2)` 2
`p^(3)` (half-filled orbital), Which allows it additional stability.

This increases the energy required to remove the first electron from N in comparison with O.
