Structure & Bonding (Double) quiz Loading... 1. Explain, in terms of its structure, why graphite can conduct electricity.Graphite has delocalised protons which can moveGraphite has layers which can easily slide over each otherGraphite has positive ions which can moveGraphite has delocalised electrons which can moveQuestion 1 of 12 Loading... 2. Explain how the atoms are held together in a hydrogen bromide moleculeA pair of electrons is transferred from bromine to hydrogenA shared pair of electrons is attracted to 2 nucleiA shared pair of electrons is attracted to one nucleusA single electron is transferred from bromine to hydrogenQuestion 2 of 12 Loading... 3. Explain the term ionic bondAn ionic bond is the strong electrostatic attraction between a shared pair of electrons and two nucleiAn ionic bond is the strong electrostatic attraction between similarly charged ionsAn ionic bond is the strong electrostatic attraction between oppositely charged ionsAn ionic bond is the strong magnetic attraction between oppositely charged ionsQuestion 3 of 12 Loading... 4. A substance is found not to conduct electricity even when molten. What type of bonding does the substance have?CovalentIonicMetallicCovalent or ionicQuestion 4 of 12 Loading... 5. Describe the structure of an ionic compound, e.g NaClA giant structure held together by the attraction between similarly charged ionsA giant structure held together by the attraction between oppositely charged ionsA giant structure held together by the attraction between positive metal ions and a sea of delocalised electronsA giant structure held together by intermolecular forcesQuestion 5 of 12 Loading... 6. Why is the boiling point of a larger molecule higher than that of a smaller molecule?Larger molecules have fewer attractions between them. These take less energy to overcome.Larger molecules have more attractions between them. These take more energy to overcome.Larger molecules have fewer attractions between them. These take more energy to overcome.Larger molecules have more attractions between them. These take less energy to overcome.Question 6 of 12 Loading... 7. Describe the formation of a covalent bondThe sharing of a single electron between two nucleiThe transfer of electrons from one atom to anotherThe sharing of a pair of electrons between two nucleiThe electrostatic attraction between positive metal ions and a sea of delocalised electronsQuestion 7 of 12 Loading... 8. How can atoms get a full outer shell?Only transfer (ionic) of electronsEither the transfer (covalent) or sharing (ionic) of electronsConversion of electrons to protonsEither the transfer (ionic) or sharing (covalent) of electronsQuestion 8 of 12 Loading... 9. In the dot and cross diagram of the outer electrons showing the covalent bonding in a molecule of oxygen (O₂), how many electrons should be shown in areas 1, 2 and 3?There should be four electrons in area 1, two electrons in area 2, and four electrons in area 3There should be four electrons in area 1, four electrons in area 2, and four electrons in area 3There should be three electrons in area 1, two electrons in area 2, and three electrons in area 3There should be two electrons in area 1, six electrons in area 2, and two electrons in area 3Question 9 of 12 Loading... 10. Do ionic substances conduct electricity?Yes, ionic substances always conduct electricityOnly when moltenNo, ionic substances never conduct electricityNot when solid, but they do when either molten or in solutionQuestion 10 of 12 Loading... 11.
