WebSo the difference in electronegativity is somewhere between 1.5 and 2.1, between a polar covalent bond and an ionic bond. So most textbooks we'll see approximately somewhere around 1.7. So if you're higher than 1.7, it's generally considered to be mostly an ionic bond. Lower than 1.7, in the polar covalent range. WebIn this review, the recent process of bonds was detailed summarized in relative areas. Meanwhile, the bonds could be divided into M C and M-X-C (M presents metal elements; C is about carbon materials; X = O, S, N etc.), and their relative physical-chemical traits with validation means have been concluded.
