Is electronegativity only in covalent bonds?

The type of bond formed between two atoms would, evidently, depend upon the difference in their electronegativities. If the difference is zero or very small, the bond formed would be covalent and if the difference exceeds 2. read more

Electronegativity values are useful in determining if a bond is to be classified as nonpolar covalent, polar covalent or ionic. What you should do is look only at the two atoms in a given bond. Calculate the difference between their electronegativity values. read more

Polarity of bonds. In a pure covalent bond, the shared electrons are equally available to each of the atoms. This arrangement occurs only when two atoms of the same element bond with each other. Thus, the hydrogen molecule, H 2, contains a good example of a pure covalent bond. In most cases, the electrons in covalent bonds are not shared equally. read more

The type of bond formed between two atoms would, evidently, depend upon the difference in their electronegativities. If the difference is zero or very small, the bond formed would be covalent and if the difference exceeds 2.5, the bond formed would be electrovalent. read more
