- Ionic Bonding
- Ionic compounds are usually formed when metals react with non metals. The ions are held together by strong forces of attraction between the oppositely charged ions which is called ionic bonding.
- The ionic bonds between the particles result in an arrangement of ions called a giant structure/ giant lattice. This structure is very regular because the ions all pack together neatly. The force in the lattice acts equally in all directions which is why the ions are all held together so strongly.
- We can represent the atoms and ions involved in forming ionic bonds through dot and cross diagrams. In these diagrams we only show the electrons in the outer shell.
- Besides the elements in groups 1 and 7, other elements that can form ionic compounds include those from groups 2 and 6.
