bonding

• Ionic bonding - bonding between 2 oppositely charged particles.
• ions with opposite charges form ionic bonds
• ionic compounds always have giant lattice structures. There are very strong electrostatic forces of attraction between opposite charges.
• Ionic compounds have high melting and boiling points due to the strong covalent bonds. The strong covalent bonds require more energy to break.
• Solid ionic compounds don't conduct electricity because the ions are fixed in place and cannot move. But when they are liquid, they can conduct electricity because the ions are free to move.
• Covalent bonding - bonding between two atoms sharing one or more pairs of electrons.
• why can't ions conduct electricity in solid but can in liquid?

  in the solid state, the ions are fixed in place and vibrate around a fixed position. but when liquid, the ions are free to move and therefore can conduct electricity.
