These compounds are ionic.
Electrostatic force of attraction
Electrostatic attraction between oppositely charged ions.
strengths of attraction between the particles in the compounds
In an ionic compound, atoms transfer electrons from one to the other, creating oppositely charged ions. The ionic bond is an electrostatic attraction between the oppositely charged ions. Ionic compounds tend to form between metals and nonmetals. In covalent compounds, atoms share electrons. Most covalent compounds form between nonmetals.
Ionic compounds are hard and rigid due to strong forces of attraction between the oppositely charged ions. Ionic compounds have high melting and boiling points, again due to strong forces of attraction between the ions. Ionic compounds dissolve easily in water.
They are held together in a lattice structure by ionic bonds
As the distance decreases the attraction increases
The answer depends on if they are atoms or in an ionic bond. In an ionic bond oppositely charged ion are held together by the electronic force of attraction that exists between oppositely charged particles.
Ionic (electric) attraction forces of (sodium) Na+ and (chlorine) Cl- ions. (i.e. of oppositely charged particles)
magnetism
An attraction between particles of the SAME substance is called cohesion.
electrostatic force of attraction between the positive cations and the negative anions.
