The high covalent characted is just explained by the fact of $\ce{Pb^{4+}}$ being very polarizing and $\ce{Cl-}$ fairly polarizable. My answer: The inert pair effect in P b causes it to pull back the electrons, resulting in polarisation. My point is, if we don't think of the inert pair effect, we are generalising this, and moreover, high ionisation energies of lead should be explained by the inert pair effect. Periodic table labeled (14 different labeled images), Periodic table with electronegativity values, Protons neutrons and electrons of all elements.

One good example is ligand field theory, which is still useful even when molecular orbitals theory is more accurate and can still explain the same (and many more) things than the former. Chemical bond. A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. Is a copyright claim diminished by an owner's refusal to publish? Classify each of the following compounds as either ionic or covalent. Cu+ They are used in manufacturing of active paste for lead-acid batteries. This electrostatic force between Ba ion and SO4 ion results in an ionic bond between them. Covalent bonding is the sharing of electrons between atoms. This bonding occurs primarily between nonmetals; however, it can also be observed between nonmetals and metals. There are better models and orbital calcualtions that can also do the job? Rules For . C. most ionic compounds are insoluble in water How do two equations multiply left by left equals right by right? To tell if H2SO4 is ionic or covalent (also called molecular) we look at the Periodic Table that and see that S and O are non-metals and H is also a non-metal. As mentioned above, you can simply remember that when the metal combines with nonmetal, the bond between them is an ionic bond. Halogenides with metals in high oxidation state are rarely truly ionic on their own, as a strong positive charge on the cation must be stabilized. 4. So, usually higher halogenides are either molecules with highly polar bonds or (di/oligo/poly)mers with highly polar bonds where some halogen atoms participate in two metal-halogen bonds.
