Magnesium fluoride contains only magnesium and fluorine. what is the formula for this compound? express your answer as a chemica
l formula

Explanation:
Atomic number of magnesium is 12 and its electronic configuration is 2, 8, 2. So, to acquire stability it loses 2 valence electrons and hence forms ion.
Whereas atomic number of fluorine is 9 and its electronic distribution is 2, 7. And, to attain stability its needs to gain one electron and hence then it forms ion.
Therefore, when both magnesium and fluorine chemically combine together then magnesium atom will donate its 2 valence electrons to the fluorine atom.
Hence, they will tend to form magnesium fluoride, that is, .

The arrangement of molecules within the 3 phases of matter are shown in the picture.
For the solid, the molecules are packed closely together. They don't have much space to move, so they just practically vibrate. For the liquid, the molecules are relatively farther from each other. The liquid molecules can flow freely but not as much as the gases. In the gases, the molecules are very far from each other. They are very sensitive to slight changes of pressure, volume and temperature.

Boiling point of a compound is determined by the strength of intermolecular forces of attraction between the molecules present in it. Stronger the intermolecular forces of attraction, higher will be the boiling point.
Ionic compounds show ion-ion interactions which are the strongest among all. Ion-dipole interactions are shown when ionic solutes are dissolved in polar solvents. Hydrogen bonding is also a relatively stronger force that is present between H atom and an electronegative atom like F, O and N() . All polar molecules show dipole-dipole interaction (
and
). Dispersion forces are the weakest intermolecular forces due to momentary dipoles between electron clouds and nucleus.
Among the given compounds, has dispersion forces as the major intermolecular forces of attraction. So they they exhibit the weakest IMF, hence have the lowest boiling point.
