Explain, in terms of the arrangement of electrons in its atoms, why neon is very unreactiveNeon is a noble gasNeon has 8 electrons in the outer shell, so it is full. Therefore it does not easily gain or lose electronsNeon has an even number of electrons so it does not need to form bondsNeon has the same number of electrons and protons so it is unreactiveQuestion 2 of 23 Loading... 3.

State the colour change observed when bromine is added to an aqueous solution of potassium iodideno changeorange to colourlessbrown to orangeColourless to brownQuestion 6 of 23 Loading... 7. On the Periodic Table what is the meaning of the word Period?A Period is a vertical column of similar elementsA Period is a collection of elements with the same number of electrons in the outer shellA Period is a horizontal row of elementsA Period is a collection of similar elementsQuestion 7 of 23 Loading... 8. Explain, in terms of electrons, why isotopes have the same chemical propertiesIsotopes are radioactiveIsotopes have the same number of protons but a different number of neutronsIsotopes have the same number of electronsIsotopes have different massesQuestion 8 of 23 Loading... 9. What is sacrificial protection?Sacrificial protection is when a more reactive metal is close to a less reactive metal. Only the less reactive metal corrodes, so protecting the more reactive metalSacrificial protection is when a more reactive metal is close to a less reactive metal. Only the more reactive metal corrodes, so protecting the less reactive metalSacrificial protection is when a more reactive metal is connected to a less reactive metal. Only the less reactive metal corrodes, so protecting the more reactive metalSacrificial protection is when a more reactive metal is connected to a less reactive metal. Only the more reactive metal corrodes, so protecting the less reactive metalQuestion 9 of 23 Loading... 10. 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 2,1. 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 2,1. 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 2,8,8,1. 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 sodiumQuestion 10 of 23 Loading... 11. How many electrons in the outer shell of group 7 elements?6784Question 11 of 23 Loading... 12. If 2 similar test tubes contain acid, and a different metal sample is added to each, how might you tell which metal is more reactive?Fewer bubbles appear in the test tube with the more reactive metalThe metal that disappears fastest is the less reactive metalMore bubbles will appear faster in the test tube with the more reactive metalThe test tube with the more reactive metal will turn cloudy fasterQuestion 12 of 23 Loading... 13. 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 number of electrons in the outer shellSame electronic configurationSame number of electron shellsSame number of electrons in the inner shellQuestion 13 of 23 Loading... 14. What colour and state is bromine at room temperature?Orange liquidRed-brown liquidBrown gasGrey solidQuestion 14 of 23 Loading... 15. Which gas will turn damp red litmus paper blue?HydrogenChlorineAmmoniaCarbon dioxideQuestion 15 of 23 Loading... 16. 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 further from 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. The outer shell of bromine is further from the nucleus, so the attraction is stronger, making it less reactive.Both chlorine and bromine react by their nucleus attracting an electron to fill their outer shell.

Write the chemical equation for the reaction betweem sodium and water2Na + 2H₂O → 2NaOH + 2H₂2Na + H₂O → Na₂OH + H₂Na + 2H₂O → 2NaOH + H₂2Na + 2H₂O → 2NaOH + H₂Question 19 of 23 Loading... 20. If pieces of lithium, potassium and sodium were cut and exposed to air, how could observations of the different reactions indicate the relative reactivity of those 3 metals?Potassium would burn with a lilac flame showing it is least reactive. Lithium would not burn at all showing it is most reactiveSodium would oxidise the most quickly, showing it is most reactive. Lithium would oxidise the slowest, showing it is least reactive.Potassium would oxidise the most quickly, showing it is most reactive. Lithium would oxidise the slowest, showing it is least reactive.Potassium would burn with a lilac flame showing it is most reactive.
