Which of the following statements is false about the structure and bonding in metals?The delocalised electron cannot move freely throughout the structure.Atoms in metals are arranged in a regular pattern.The strong metallic bond is due to the sharing of the delocalised electrons between positive metal ions.There is an electrostatic attraction between the delocalised electrons and metal ions.

Which of the following statements about metallic bonding is true?Statement 1: In metallic bonding, the metal ion is negatively charged and the delocalised electrons are positively charged.Statement 2: In metallic bonding, there is a repulsion between the metal ion and the delocalised electrons.Statement 3: The sharing of the delocalised electrons between the metal ions causes the metallic bond to be strong.None of the statementsStatement 2 and 3 onlyStatement 1 onlyStatement 3 only

The strength of the metallic bond is due to which one of the following?The free movement of the delocalised electrons throughout the metal.The presence of oppositely charged particles.The arrangement of metal atoms in a regular pattern.The sharing of the delocalised electrons between metal ions.

Complete the sentence:Metallic bonding is…… the electrostatic attraction between positive metal ions and negative delocalised electrons.… the electrostatic attraction between oppositely charged metal ions.… the sharing of electrons between the positive metal ion and the negative delocalised electron.… the sharing of pairs of electrons.

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
