Answer :
An element's electronegativity determines whether it is ionic or non-ionic. Fluorine has the most electronegativity while iodine has the lowest, which means that the Cs I ionic bond's power of attraction is at its lowest, allowing for the largest possible distance between their molecules.
By intermolecular contact, what do you mean?
The attracting and repellent forces that develop between the molecules of a substance are referred to as intermolecular forces (IMF), which is sometimes shortened. These forces act as a bridge between the individual molecules of a substance. Intermolecular forces are primarily responsible for the physical and chemical properties of matter.
Which four intermolecular interactions are there?
The following are the four main intermolecular forces: Van der Waals dipole-dipole interactions < Van der Waals dispersion forces <Ionic bonds <Hydrogen bonds .
