The valence electrons of an atom are found in its outermost shell, or energy level. Nitrogen is in the second period of the periodic table, which means its outermost electrons are in the second energy level.

Looking at the options:

A. 3p only - This is incorrect because nitrogen's outermost electrons are in the second energy level, not the third.

B. 2s only - This is partially correct. Nitrogen does have electrons in the 2s sublevel, but not only there.

C. 2s and 3p - This is incorrect because, as mentioned earlier, nitrogen's outermost electrons are in the second energy level, not the third.

D. 2s and 2p - This is the correct answer. Nitrogen has two electrons in the 2s sublevel and three electrons in the 2p sublevel. These five electrons are its valence electrons.
