Why Nacl has High Melting point, due to the strong electrostatic attraction forces between positive and negative ions, Why Ammonia is bad conductor of electricity, due to no free moving electrons, Why graphite is good conductor of electricity, due to free moving electrons, Why Diamond has a high melting point, Due to the strong covalent bonds, Why copper has a high melting point, due to the strong electrostatic attraction forces between positive ions and negative electrons, Why NaCl is good conductor only when liquid, When liquid there are free moving ions, Why Methane(CH4) has a low melting point, Due to the weak intermolecular forces, Why Magnesium is a good conductor of electricity, Due to the sea of the delocalizied electrons, Why graphite is soft, Layered structure and layers slide over each other, Why diamond is used in drilling, because it is hard and has a giant tetrahedral structure
