Ionic bonds are electrostatic attractions between oppositely charged atoms. These bonds typically form between a metal and a non-metal, where the metal loses electrons to become positively charged and the non-metal gains those electrons to become negatively charged.
Molecules that do not have oppositely charged ends are nonpolar molecules.
When molecules are close together, a slight attraction can develop between the oppositely charged regions of nearby molecules. Chemists call such intermolecular forces of attraction van der Waals forces. (This also occurs in the phenomenon known as Hydrogen-bonding.) What is the alternate of a slight attraction - it is called the covalent bond. Note that an ionic bond is a type of covalent bond.

Molecules that do not have oppositely charged ends are nonpolar molecules.
Polar molecules are attracted to the oppositely charged metal plates due to the electrostatic forces. The molecules will align themselves with the electric field between the plates, causing the plates to exhibit slight dipole moments. This can lead to changes in the properties of the molecules, such as increased polarity or reorientation of molecular orientation.
Those molecules are polar.
Nonpolar molecule is one which electrons are shared equally in bonds. Such a molecule does not have oppositely charged ends. This is true of molecules made from two identical atoms or molecules that are symmetric, such as CCl4.
No, attractions among ions within a crystal lattice are strong due to the electrostatic forces between oppositely charged ions. These attractions create a stable structure that gives crystals their rigidity and specific properties.
This could be a catch question! NaBr is ionic and there are no molecules. The inter ionic forces are electrostatic.
