WHICH one is the strong compound, the one which transfers or shares more electrons # "OR" # the one which transfers or share less electrons?

I want the idea for both the ionic and covalent compounds.

You are asking us to compare ionic bonding to covalent bonding......


Ionic bonding results from the transfer of electrons between species to form positively charged, and negatively charged ions. In the resultant ionic structure, each CATION is electrostatically bound to every other ANION in the lattice. Of course, each cation is also electrostatically repelled by every other cation, but if you add up attractive versus repulsive electrostatic interactions ACROSS the ENTIRE lattice, which may certainly be done quantitatively, attractive interactions predominate, with a non-molecular ionic solid resulting.

This #"non-molecularity"# is the most important factor in the properties of an ionic solid, as compared to molecular materials. Non-molecular species, ionic crystals, and covalently bound non-molecular materials such as quartz, and carbon (graphite and diamond), tend to have exceptionally high melting and boiling points. In these latter materials bonding is to a first approximation covalent, with a region of high electron density BETWEEN two positively charged nuclei.

On the other hand, for discrete molecules, i.e. ethane, glucose, phosphorus trichloride, hexanes, even water, there are marginal interactions between molecules, and these materials tend to have low to moderate melting and boiling points as a consequence.
