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.
let me see the answer please

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, two positives are repelling, not attracting. No. Compounds are formed by two or more different elements. An ionic compound is formed by the attraction between two oppositely charged ions. Molecular compounds are formed by the sharing of electrons between atoms, which is called a covalent bond.
There are a few ways to calculate this, but for two point charges, such as two oppositely charged atoms the easiest way is to use Coulomb's law:where:F = the force of attractionq_1 = the charge of object 1q_2 = the charge of object 2r = the distance between the center of object 1 and object2ε0 ≈ 8.854187817... × 10−12 F·m−1For two oppositely charged atoms you must know what the charge of the each atom is to complete the calculation. For this calculation I'll assume that object 1 has one more electron than a neutrally charged atom ( has a charge of 1 e-), and object two has one fewer electron than a neutrally charged atom (has a charge of e+)e = 1.602176487 x 10-19 coulombsSo if we fill everything into Coulomb's equation we can get the force of attraction between two oppositely charged atoms,
An ionic bond forms when two oppositely charged ions combine.
Polar solvents are characterized by regions with strong positive or negative electrical charges. For example water, the most usual polar solvent, is negatively charged on the oxygen end of the molecule and positively charged on the hydrogen end, simply because the oxygen nucleus attracts the shared electrons more strongly than the hydrogen nuclei do (and the hydrogen atoms are arranged at the points of a tetrahedron, rather than in a straight line with the oxygen atoms). And a typical polar solute such as sodium chloride, has positively charged sodium ions and negatively charged chlorine ions because chlorine has a much stonger attraction for electrons than sodium does, so it takes an electron from sodium. And then, given Coulomb's Law, we get an attraction between oppositely charged chemicals or portions of chemicals; the positively charged sodium ions would be attracted to the negatively charged oxygen region of the water molecule, the negatively charged chlorine ions are attracted to the positively charged hydrogen region of the water molecule. It is these electrostatic attractions which cause the solute to dissolve in the solvent.

Molecules that do not have oppositely charged ends are nonpolar molecules.

Molecules that do not have oppositely charged ends are nonpolar molecules.
Ionic bonds
Ionic substances are held together ionic bonds, which are the electrostatic attractions between oppositely charged ions.
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.
When polar molecules are placed between oppositely charged metal plates they will align themselves. They align in the direction of the field.
Those molecules are polar.
The strong ionic forces (electrostatic) of attractions that exists between the positively and negatively charged molecules keeps the ions together. remember that oppositely charged ions tend to attract. The is also weak Van der waals forces of attraction.
