Covalent Bond: Types of Bonds, Examples, Formation - Embibe 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.

CH4 lewis structure, Molecular geometry, Polar or nonpolar ... CH4 is a nonpolar molecule due to its symmetrical geometry that causes uniform charge distribution all over the atom leads to a zero net dipole moment and makes this molecule non-polar in nature. The molecular geometry or shape for CH4 is the tetrahedral with bond angle ∠H−C−H =109.5°.
