Metallic bonding always occurs between:Noble gasesMetal atomsNon-metal atomsMetal and non-metal atoms2A metallic bond is the electrostatic attraction between:Positive ions and delocalised electronsNegative ions and delocalised electronsElectrons and delocalised negative ionsElectrons and delocalised positive ions3Which of these is a property of metals?Poor conductors of electricityLow boiling pointsMalleableLow melting points4Which of the following statements best describes why metals are good conductors of heat?Metallic bonds are very strongLayers of metal atoms can slide past one another easilyMetals have high melting pointsThe delocalised electrons can carry thermal energy through the substance5Which of the following is a metal alloy?AluminiumCopperSteelIron6Metal alloys are generally harder and stronger than the individual elements they are made from. This is because the atoms of each element are of a different size and therefore:Disrupt the regular layers of ions, making them less malleableIncrease the size of the latticeLead to an increase in boiling pointLead to an decrease in boiling point

Which is the best description of metallic bonding?The electrostatic attraction between protons and electrons.The electrostatic attraction between a lattice of positive metal ions and delocalised electrons.The electrostatic attraction between positive nuclei and shared electron pairs.The electrostatic attraction between positive and negative ions.
