Answer #1

Answer: d. 3

NITROGEN belongs to Group V with 5 valence electrons 2s2, 2p3

Since Nitrogen has 5 electrons in the valence shell, so it can combine with 3 hydrogen atoms/or other atoms like carbon to form the covalent bond to fulfill the octet rule.

Leaving two electrons that are not used for bonding (if used nitrogen would have to share more than 8 electrons, which violets the octet rule).

These electrons which do not participate in bonding are called as lone pairs, unshared electrons, or nonbonding electrons.

"Understand that the number of covalent bonds an atom can form is directly related to the number of electrons in its own valence shell. How many bonds can carbon form (what is the most, what is the fewest)?" This question is from my functional bio review. Carbon can form 4 bonds is my understanding, so does that mean that the most is 4 and the fewest is 1? or 0?
