How does the valence bond theory describe a covalent bond formation? A. The valence bond theory explains that covalent bonds are formed inside an atom when inner orbitals overlap with valence orbitals.
B. The valence bond theory explains that covalent bonds are formed in the region where the atomic orbitals of two atoms overlap.
C. The valence bond theory explains that covalent bonds are formed in the region of the inner orbital when inner orbitals overlap with the valence orbitals of another atom.
