Ionic vs Covalent Bonds - Understand the Difference - ThoughtCo
Jan 23, 2020Covalent Bonds. In a covalent bond, the atoms are bound by shared electrons. In a true covalent bond, the electronegativity values are the same (e.g., H 2, O 3), although in practice the electronegativity values just need to be close the electron is shared equally between the atoms forming a covalent bond, then the bond is said to be nonpolar. Usually, an
