ionic, covalent and metallic bonding

• What happens to the electrons in a covalent bond

  Pairs of electrons are shared by atoms
• Why does graphite conduct electricity

  Graphite has delocalised electrons, just like metals. These electrons are free to move between the layers in graphite, so graphite can conduct electricity.
• What charge do metal ions form

  a positive charge
• Why do metals conduct electricity

  Metals conduct electricity because they have DELOCALISED ELECTRONS
• What are the three different types of bonding

  ionic, covalent and metallic
• What is the name given to the forces between each molecule

  intermolecular forces
• Substances formed from two or more elements chemically bonded is called

  a compound
• Which subatomic particle takes part in bonds

  electrons
• Why can ionic compounds conduct when dissolved in water

  They separate into charged ions
• What type of bonding does MgCl2 have and why

  ionic bond because MgCl2 (Magnesium chloride) is an ionic compound because when the metal combines with nonmetal, it usually forms an ionic compound. Here, Mg is a metal and Cl is a nonmetal. So when they combine, it forms an ionic compound.
