Do highly electronegative atoms form covalent bonds?
And I can name three without thinking:
Electronegativity is conceived to be ability of an atom involved in a chemical bond to polarize electron density towards itself, resulting in a polar bond, where electron density is UNEQUALLY shared. For homonuclear diatomic molecules, given that the elements have EQUAL electronegativity, there should be no charge separation, no polarity in the
On the other hand for
