← ScienceWhich outcome occurs when two atoms with half-filled valence orbitals approach to bonding distance?
A)Orbital hybridization forming sigma bonds✓
B)Nuclear fission releasing binding energy
C)Electron capture lowering atomic number
D)Neutron emission altering isotopic mass
💡 Explanation
When two atoms with half-filled valence orbitals approach, orbital hybridization occurs because their wave functions overlap constructively, leading to the formation of sigma bonding orbitals which stabilize the molecule. Therefore, sigma bond hybridization results, rather than fission, capture, or emission which don't typically occur in molecular bonding.
