WebDefine electronegativity and assess the polarity of covalent bonds Ionic bonding results from the electrostatic attraction of oppositely charged ions that are typically produced by the transfer of electrons between metallic and nonmetallic atoms. WebJan 17, 2024 · A covalent bond that has an equal sharing of electrons and the electronegativity difference is zero is called a nonpolar covalent bond. Polar Covalent Bond When the electrons spend more time around the more non-metallic atom, the sharing of the electron pair becomes unequal and results in the formation of polar covalent bonds.

WebIn covalent bonds, the participating atoms do not lose or gain electrons, but rather share them.
