Intermolecular force plays a great role in determining the state of a substance. which of these phases has the least intermolecular force?

I'm pretty sure its..

The most internolecular force between molecules is found in solids. Some solids require a lot of energy to chang state

The least intermolecular force between molecules is found (evidently) in gasses. Gas particles are free to move and fill their container. This means that between molecules there is weak attraction.

NB: Intermolecular forces may be weak in compounds, this does not mean that the bonds WITHIN molecules are weak. You can have strong covalently bonded molecules for example, but that have weak intermolecular sorces of attraction between the molecules.

i do hope this helps you out.

the atomic number of magnesium is 12. its nucleus must contain 12 protons and no electrons. the atomic number of an atom is determined by the number of protons.

magnesium is an electrolyte injection commonly used to treat low magnesium levels in your blood. it is also used to prevent or control seizures in women with preeclampsia or eclampsia.
