What three elements can hydrogen bond with to create the IMF of Hydrogen bonding between molecules? True or False? This electronegativity difference results in the formation of polar covalent bonds, albeit, the molecule in itself is non-polar. In particular, the C-O bond is much more covalent than Si-O, so that considering a formal C 4 ion, as is some- times done for Si 4+, is out of the question. Weakest? In a bond, the atoms gain, lose, or share their electrons depending upon their requirement. Why is an ionic bond a chemical and not a physical bond? As we have already studied in the earlier section, the ionic bonds are formed when the electronegativity difference is above 1.6 while covalent bonds are formed when it is below 1.6.
