Polarizability
What is polarizability and what is its significance to interactions between ions and molecules?

Re: Polarizability
Polarizability is a measure of how easy an electron cloud is distorted by an electric field. The electron distortion is proportional to the polarizability of the electron.

Re: Polarizability
Polarizability depends on the number of electrons present and on the size of the pertinent atom. Higher polarizability means that the atom or ion has a more readily distortable electron cloud; the process of distortion itself is known as polarization.

Re: Polarizability
In addition to this, I believe that the more polarizable an atom is, the stronger the bond it will form with another atom.

Re: Polarizability
Polarizing power is the ability of a cation to distort an anion(like to which extent an atom can affect another atom), while polarizability is the ability to form instantaneous dipoles(How much the atom itself can be affected).

Re: Polarizability
It's important to note that the more Polarizability an element has means the more electrons it has which means it is more distorted and the electrons are less tightly held. An example the professor uses is going from Helium to Xenon, Xenon has more electrons and has more polarizability.

Yes, Polarizability is the ability to form instantaneous dipoles. Dipoles form when a molecule has a positive charge and a negative charge such as Na+Cl-. Also in hydrogen bonding it's also important to note that Hydrogen has an alpha positive charge and is attracted to alpha negative such as N,O,F atoms.
