Why do ionic bonds form? Is nitrogen ionic or covalent? Why is bond breaking endothermic? How does a polar covalent bond contribute to formation of hydrogen bond? Why is the C=O double bond so much more polar than the C-O single bond? Why do hydrogen and oxygen bond? Why do BF3 and...
Y (X =LiF,NH3,H2 O;Y =HF,LiF) complexes were optimized at CCSD (T)/ccpVTZ level.The results of natural atomic charges,Wiberg bond index and localized molecular orbitals suggest that H-F bond in HFLiF is covalent,but Li-F bond is more like ionic instead of covalent.The bind energy...

[V-EX(X,N)] of the interacting quantum atoms (IQA) scheme, could constitute a quantitative measure of the covalence of these molecular interactions; (iii) both classical electrostatic and quantum exchange show high values, indicating that strong ionic and covalent contributions are not mutually ...

Li is also the weakest N binder among s-metals, very electropositive element, and Li-N bonds in Li3N have a strong ionic character (Greenwood and Earnshaw, 1997). Li therefore releases N much easier than other s-metals,. The bonds of other s-metals have a more covalent character, ...
For metal complexes with the same spin-state, the centroid of the Kβ1,3 feature can be correlated with the covalent (vs. ionic) character of the metal-ligand bond; it has been reported that Kβ1,3 emission shifts to higher energies with increasing ionic character [38]. This is seen ...

Is HCl an ionic bond? How many bonds does nitrogen form? Is PCl3 covalent or ionic? Are hydrogen bonds polar or nonpolar? What is the IUPAC name for NH3? What kind of bond is a hydrogen bond? How are ionic and covalent bonds different from hydrogen bonds? Why does water form hydrogen...
Covalent "H-X" bonds are the basis of the Bronsted-Lowry theory of acids and bases. One or more of these bonds are dissociated to an appreciable degree from each particle of an acidic substance. This releases an ionized hydrogen atom (proton). A basi...
