Match the correct explanation to the property of pure metals it explains. High densityHigh melting pointMalleableThermal conductivitySolid at room temperaturePossible AnswersWhen the metal is in the solid state the particles are tightly packed together and held in a fixed positions.The layers of metal atoms can slide over each other when a force is applied.A lot of energy is needed to overcome the strong electrostatic attraction between the metal ion and the delocalised electron.This is due to the high boiling and melting points.The delocalised electrons are free to move and can transferenergy.A lot of energy is needed to overcome the weak electrostatic attraction between the metal atom and the delocalised electron.The delocalised electrons are free to move and can carry anelectric current.I DON'T KNOWRESETSUBMIT ANSWER

Pure metals have high melting and boiling points.Which one of the following would you expect to have the highest melting point?NitrogenTungstenFluorineSulfur

Explain why ionic substances have high melting points.

There are very strong electrostatic forces of attraction in all directions in a giant ionic lattice.Why does this result in a very high melting point?A lot of energy is needed to overcome the electrostatic forces and separate the electrons from each other.A lot of energy is needed to overcome the electrostatic forces and hold the ions together.A lot of energy is needed to overcome the electrostatic forces and separate the atoms from each other.A lot of energy is needed to overcome the electrostatic forces and separate the ions from each other.
