Polarizability
Does polarizability follow the same trend as atomic size? Are there any exceptions? Why do they follow the same trend?
Re: Polarizability
Polarizability increases as the size of the anion increases. The larger electrons cloud, the more susceptible it can be distorted since the electrostatic attraction of the outer electrons being reduced.

Re: Polarizability
Yes polarizabilty does increase with atomic radius and charge, but it also increases with atoms that have lower electronegativity, which means the outer electrons feel less of a pull from the nucleus and thus are more likely to get distorted and form covalent bonds with cations.
Hope this helps!

Re: Polarizability
Yes! You are correct. Polarizability increases as molecular mass increases because, as molar mass increases so does the number of electrons in an atom. The more electrons there are, the more polarizability an atom has.

Re: Polarizability
Polarizability increases with the size of the electron and how many electrons it has. For example, Iodine has high polarizability because it is a big atom with many electrons compared to something like sodium.

Re: Polarizability
Polarizability is the ability of an atom to form instantaneous dipoles. Thus, when an atom has a bigger atomic radius, it's polarizability increases because there are more electrons and the electrons are more dispersed.
