· In ionic bonding the atoms involved lose or gain electrons so they have a noble gas structure.
· If you gain an electron it is a negative ion, if you lose an electron, it is a positive ion
· Ionic compounds are usually formed when metals react with non metals.
· The ions formed are held with enormously strong forces of attraction between the oppositely charged ions. This electrostatic force of attraction, which acts in all directions, is called an Ionic Bond.
· An ion is a charged atom or molecule. It is charged because the number of electrons does not equal the number of protons in the atom.
· The ionic bonds between the charged particles results in an arrangement of ions we call a giant structure.
· The force exerted by an ion on the other ions in the lattice acts equally in all directions. This is why the ions in a giant structure are held together so tightly.
· The giant structure of ionic compounds is very regular. This is because the ions all pack together neatly.
