Polairzability characteristics

Postby Nick Fiorentino 1E » Sat Nov 09, 2019 6:18 pm

In lecture on Friday, Lavelle said that if an atom is highly polarizable, it is solid at room temperature. Why is this?

I think that the more polarizable the atom is, the more the covalent bond will have ionic characteristics, and ionic bonds are usually solid.

Also, the more polarizable an atom or molecule is, the greater the intermolecular induced-dipole induced-dipole forces. Since those forces are greater, it takes more energy to reach the liquid or gas phase.
Ex: Cl2 is a gas at room temperature because the interactions between the Cl2 molecules are weak whereas since I2 is larger and more polarizable, the interactions between I2 molecules are stronger and it is solid at room temperature.

It is harder to break the bonds in a more polarizable atom and covert it to a liquid or gas.
