Molecular Bonds: Covalent, Ionic & Metallic Covalent Bonds: Directional sharing of electrons, involving hybrid orbitals (e.g., in H 2 , CH 4 ). Ionic Bonds: Electron transfer creates oppositely charged ions held by electrostatic attraction (e.g., NaCl). Metallic Bonds: Delocalized “sea” of electrons around positive ion cores, giving rise to conductivity and malleability. Molecula...
