Response:
A covalent bond is formed when the outer electrons of two atoms are shared, enabling them to adequately fill their orbitals.
Clarification:
Covalent bonds occur between atoms with an electronegativity difference below 1.7. In this bonding type, one atom's valence electrons create a molecular bond with the other atom's valence electrons, leading to mutual sharing of electrons.
Covalent bonds can be non-polar, as seen in hydrogen and carbon bonding.
Conversely, covalent bonds can also be polar, such as the bond between hydrogen and chlorine, where the chlorine atom is more electronegative and draws electrons towards itself, resulting in a lower electron density on the hydrogen atom.
