What is galvanising?When iron is layered inside a less reactive metal to prevent that metal from corrodingWhen zinc is used to coat a less reactive metal to prevent that metal from corrodingWhen zinc is layered inside a less reactive metal to prevent that metal from corrodingWhen iron is used to coat a less reactive metal to prevent that metal from corrodingQuestion 2 of 23 Loading... 3. If pieces of lithium, potassium and sodium were added to water, how could observations of the different reactions indicate the relative reactivity of those 3 metals?Sodium would bubble the least vigorously, showing it is least reactive. Lithium would give off a orange flame, showing it is most reactive.Lithium would bubble the most vigorously, showing it is most reactive. Potassium would give off a lilac flame, showing it is least reactive.Sodium would bubble the least vigorously, showing it is least reactive.

What does that tell us about the electron configuration of the atom?same number of electrons in the outer shellsame number of electron shellsSame electronic configurationSame number of electrons in the inner shellQuestion 12 of 23 Loading... 13. Write the word equation to represent the reaction between hydrochloric acid and calciumhydrochloric acid + calcium → calcium chloride + hydrogenhydrochloric acid + calcium → calcium chloride + waterhydrochloric acid + calcium → calcium hydrochloridehydrochloric acid + calcium → calcium hydrochloride + waterQuestion 13 of 23 Loading... 14. Where are the transition metals on the Periodic Table?Top left cornerIn the middleScattered across itLeft hand colunmQuestion 14 of 23 Loading... 15. Explain, by referring to the electronic configurations, why potassium is more reactive than sodium.Sodium has the electronic configuration 2,8,1 and potassium has 2,8,8,1. The outer electron lost from potassium is closer to the nucleus therefore the electron is more attracted by the nucleus. So potassium is more reactive than sodiumSodium has the electronic configuration 2,8,1 and potassium has 2,8,8,1. The outer electron lost from potassium is further from the nucleus therefore the electron is less attracted by the nucleus. So potassium is more reactive than sodiumSodium has the electronic configuration 2,8,1 and potassium has 2,1. The outer electron lost from potassium is further from the nucleus therefore the electron is less attracted by the nucleus. So potassium is more reactive than sodiumSodium has the electronic configuration 2,8,1 and potassium has 2,1. The outer electron lost from potassium is closer to the nucleus therefore the electron is more attracted by the nucleus. So potassium is more reactive than sodiumQuestion 15 of 23 Loading... 16. Which is less reactive: potassium or caesium?Depends on the pressurePotassiumCaesiumDepends on the temperatureQuestion 16 of 23 Loading... 17. How are elements arranged in the periodic table?in order by sizein order by atomic numberin no particular orderin order by mass numberQuestion 17 of 23 Loading... 18. If an element doesn't conducts electricity, is it a metal or a non-metal?Depends on conditionsMetalEither metal or non-metalNon-MetalQuestion 18 of 23 Loading... 19. An experiment investigates which of metals X and Z is more reactive. The result is X + ZSO₄ → XSO₄ + Z. Which metal is more reactive?ZXSO₄XZSO₄Question 19 of 23 Loading... 20. What are the elements in group 7 called?HalogensAlkali metalsNoble gasesChalcogensQuestion 20 of 23 Loading... 21. Describe the conditions under which iron rustscarbon dioxide onlyoxygen and waterwater and carbon dioxideoxygen onlyQuestion 21 of 23 Loading... 22. Explain why bromine is less reactive than chlorineBoth chlorine and bromine react by their nucleus attracting an electron to fill their outer shell. The outer shell of bromine is closer to the nucleus, so the attraction is weaker, making it less reactive.Both chlorine and bromine react by their nucleus attracting an electron to fill their outer shell.
