Explain, in terms of the arrangement of electrons in its atoms, why neon is very unreactiveNeon is a noble gasNeon has an even number of electrons so it does not need to form bondsNeon has 8 electrons in the outer shell, so it is full. Therefore it does not easily gain or lose electronsNeon has the same number of electrons and protons so it is unreactiveQuestion 2 of 22 Loading... 3. How can atoms get a full outer shell?Either the transfer (covalent) or sharing (ionic) of electronsEither the transfer (ionic) or sharing (covalent) of electronsConversion of electrons to protonsOnly transfer (ionic) of electronsQuestion 3 of 22 Loading... 4.

Explain, in terms of electrons, why isotopes have the same chemical propertiesIsotopes have different massesIsotopes have the same number of electronsIsotopes are radioactiveIsotopes have the same number of protons but a different number of neutronsQuestion 6 of 22 Loading... 7. 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 oppositely charged ionsAn ionic bond is the strong electrostatic attraction between similarly charged ionsAn ionic bond is the strong magnetic attraction between oppositely charged ionsQuestion 7 of 22 Loading... 8. Why do elements in the same group of the periodic table have similar chemical properties?Elements in the same group of the periodic table have the same number of electrons in their outer shellElements in the same group of the periodic table have different numbers of electrons in their outer shellElements in the same group of the periodic table are all the same type of element (metal, non-metal etc.)Elements in the same group of the periodic table have the same number of protonsQuestion 8 of 22 Loading... 9. What is special about the elements in group 0?They are all coloured gasesThey are all diatomicThey are very unreactive (because they have full outer electron shells)They have the same number of electronsQuestion 9 of 22 Loading... 10. On the Periodic table what is the meaning of the word Group? What does that tell us about the electron configuration of the atom?Same electronic configurationSame number of electrons in the inner shellsame number of electrons in the outer shellSame number of electron shellsQuestion 10 of 22 Loading... 11. Explain why magnesium oxide has a higher melting point than sodium chloride.Magnesium and oxygen are more reactive elementsMg²⁺ and O²⁻ ions have a higher charge than sodium and chloride therefore the electrostatic forces between the ions are much stronger. This requires more energy to break.Sodium chloride is a simple molecular substance so there are only weak intermolecular forces which require little energy to breakMg²⁺ and O²⁻ ions are larger than sodium and chloride therefore the electrostatic forces between the ions are much stronger. This requires more energy to break.Question 11 of 22 Loading... 12. Describe the structure of an ionic compound, e.g NaClA giant structure held together by the attraction between oppositely charged ionsA giant structure held together by the attraction between similarly charged ionsA giant structure held together by intermolecular forcesA giant structure held together by the attraction between positive metal ions and a sea of delocalised electronsQuestion 12 of 22 Loading... 13.
