Bonding (E (could you give examples of substances that have a giant…

- - - - giant covalent structures have high melting points due to strong intermolecular forces which require a lot of heat energy to be broken hence they have a higher melting and boiling point.
  - - - Ionic bonds are the electrostatic forces of attraction between oppositely-charged ions. The oppositely-charged ions are arranged in a regular way to form giant ionic lattices. Ionic compounds often form crystals as a result. The illustration shows part of a sodium chloride (NaCl) ionic lattice.
  - - - sodium bonded to six chlorine, and chlorine bonded to 6 sodium. therefore the coordination number of NaCl is 6
  - - - ionic structure conduct electricity in liquid or aqueous because the electrons are delocalised , and flow in the same direction when a charge is applied.
- - - - why are simple molecular structures generally gases and liquids at room temperature?
        
        Simple molecular structures are generally gases and liquids at room temperature because although they have strong covalent bond s they have weak intermolecular forces of attraction between the molecules which are easily broken with a low amount of heat energy, hence they have low melting and boiling points, hence why they are generally liquids and gases at room temp
  - - - How do you describe a simple molecular structure
        
        The simple molecular structure is made up of individual molecules. The molecules have strong covalent bonds within their molecules, but weaker intermolecular forces between molecules.
      - what is a molecule?
        
        a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
- - - - the charge on an aluminium ion is 3+ and the charge on a nitride ion is 3-.
