polarizability

[Adam Kramer 1A]

What causes different polarizability of molecules, and why does that affect a molecule being solid or liquid at room temperature?

[alexfwang3g]

The respective sizes of the molecules usually determines the molecule's polarizability - its ability to be polarized. Larger elements such as I usually are easily polarized instead of smaller elements like F.

Polarizability doesn't necessarily determine the state of the molecule, but instead it is the bonds between the molecules, whether it be hydrogen, dipoledipole etc.. that determines it.

[Rebecca Epner 4A]

Polarizability also explains the likelyhood of a certain atom to become distorted. This is why larger atoms have a higher polorizability

[Frederick Keith_4C]

Polarizability is a measure of how easily distorted an electron is by an electric field. Larger atoms with smaller negative charges are easily polarizable and can have stronger Van Der Waals interactions.

[Areena H 2K]

The size and charge of an ion determines its polarizability. The larger anion has a larger electron cloud that can be distorted and also has a lot of electrons shielding it from its nucleus therefore if another cation is close by its strong nuclear pull is going to attract the anions large electron cloud towards itself and is going to distort it.

Polarizablility increases generally when volume occupied increases. This means, as a periodic trend, it increases down a group, but decreases across a period. Polarizability determines what kinds of bonds the atom will form, which then determines the state of the molecule.

I don't really understand this too. Like how does it relate to melting and boiling point?

[Joowon Seo 3A]

The size of the molecule generally affects polarizability. When polarizability of molecules increase the energy of bonds between molecules increase resulting in higher melting and boiling points.

[Christine Honda 2I]

When polarizability of molecules increases, it takes more energy to break the stronger bonds between molecules resulting higher melting and boiling points.

Polarizability determines the strength of the bonds. The stronger the bonds, the more energy is required for a change in state (from solid to liquid or liquid to gas).
