A covalent bond involves:
AElectrostatic attraction between ions
BSharing of an electron pair between two atoms
CTransfer of an electron from cation to anion
DSharing of an electron pair from one atom only
Answer & Solution
Correct answer: B. Sharing of an electron pair between two atoms
1. Covalent bonding: sharing of an electron pair between two atoms, drawn together by mutual attraction to the shared pair.
2. Both atoms contribute one electron each to the shared pair.
3. Coordinate covalent bond (dative) is the variant where ONE atom supplies both electrons.
