A nonpolar covalent bond forms between two atoms that:
Atransfer electrons completely from one atom to the other
Bshare the bonding electron pair equally between them
Crepel each other's electrons entirely
Dalways belong to two different elements
Answer & Solution
Correct answer: B. share the bonding electron pair equally between them
1. The polarity of a covalent bond depends on how evenly the bonding electrons are shared between the two atoms.
2. The text states: "Nonpolar covalent bonds form between two atoms of the same element or between different elements that share electrons equally."
3. Complete electron transfer describes ionic bonding, not covalent bonding, and bonding atoms attract (not repel) the shared electron pair.
4. So a nonpolar covalent bond specifically involves equal sharing of electrons between the bonded atoms.
