Physical properties

[605324529]

Based on how the periodic table is organized, can you identify some of the physical properties that are associated with the ionic and covalent character?

[Chem_Mod]

Yes, electronegativity, as we discussed in Chem 14A.

[Nan_Guan_1L]

I think compounds bonded together by ionic bonds generally have higher boiling points; and also they can conduct electricity when dissolved in water, but covalent compounds can't.

[Thomas Vu 1A]

Ionic compounds also tend to be brittle since they're usually made up of crystals. Also, while ionic compounds have high boiling points and melting points, covalent compounds have low boiling and melting points.

[Karina Grover 1A]

Ionic bonds are very difficult to break (they require a lot of energy) so, therefore, they have high boiling and melting points. The substances they make up tend to be harder/more brittle too.

Covalent bonds are generally less difficult to break so they have lower boiling and melting points. The substances they make up tend to be softer/less strong too.
