WebIonic bonds occur when electrons transfer from a metal to a nonmetal. Polar covalent bonds occur between nonmetals that have large differences in electronegativity. The electrons in polar covalent bonds are found on average closer to the more electronegative atom. Nonpolar covalent bonds occur between nonmetals that have small or no ...

WebAdditionally ionic compounds don't exist as individual molecules (as their formula unit suggests) but as a repeating pattern of these formula units in a lattice. So you can use Lewis structures for ionic compounds too, but the bonding is different enough from covalent compounds that it's simply not used to the same amount. Hope that helps. WebIonic compounds have high melting and boiling points, and they tend to be hard and brittle. Ions can be single atoms, as the sodium and chlorine in common table salt (sodium chloride), or more complex (polyatomic) groups such as the carbonate in calcium carbonate. But to be considered an ion, they must carry a positive or negative charge.
