In a diatomic molecule with two identical atoms, there is no difference in electronegativity, so the bond is nonpolar or pure covalent. When the electronegativity difference is very large, as is the case between metals and nonmetals, the bonding is characterized as ionic.
If the atoms that form a covalent bond are identical, as in H 2, Cl 2, and other diatomic molecules, then the electrons in the bond must be shared equally. We refer to this as a pure covalent bond. Electrons shared in pure covalent bonds have an equal probability of being near each nucleus.

A covalent bond is a shared pair of electrons, electrostatically attracted to the positive nuclei of two atoms. Atoms can share electrons in order to achieve a stable outer electron arrangement...
Pure covalent and polar covalent. Pure covalent are bonds between two elements with identical electronegativities. For these bonds, the electrons are perfectly equally shared between the two atoms.
Pure covalent bonds, polar covalent bonds and ionic bonds all exist as part of the same bonding continuum. The type of bonding present in a compound is determined by the differences in...
A polar covalent bond is a bond formed when a shared pair of electrons are not shared equally. This is due to one of the elements having a higher electronegativity than the other. The shared pair...
