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.

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

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 2  (half-filled  orbital), Which allows it additional stability.

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

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
