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 electron shellsSame electronic configurationsame number of electrons in the outer shellSame number of electrons in the inner shellQuestion 7 of 23 Loading... 8. 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 the same number of electrons and protons so it is unreactiveNeon has 8 electrons in the outer shell, so it is full. Therefore it does not easily gain or lose electronsQuestion 8 of 23 Loading... 9. Explain, by referring to the electronic configurations, why fluorine is more reactive than chlorineFluorine has the electronic configuration 2,8,7 and chlorine has 2,7. An extra outer electron is gained more easily by fluorine. This is because the outer shell is closer to the nucleus, so an extra electron is attracted more strongly. So fluorine is more reactive than chlorineFluorine has the electronic configuration 2,8,7 and chlorine has 2,7. An extra outer electron is gained more easily by chlorine.

Describe the test for carbon dioxide gasTurns damp red litmus paper blueTurns moist litmus paper white (bleaches)Relights a glowing splintBubble the gas through limewater and see if it goes cloudyQuestion 10 of 23 Loading... 11. If a substance loses oxygen in a reaction how is the process described?CombustionOxidationHydrolysisReductionQuestion 11 of 23 Loading... 12. Where are non-metals found on the periodic table?At the top right, plus hydrogenOnly on the bottom rowOnly in the left hand columnOn the left, reaching across the middleQuestion 12 of 23 Loading... 13. 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 metalMore bubbles will appear faster in the test tube with the more reactive metalThe metal that disappears fastest is the less reactive metalThe test tube with the more reactive metal will turn cloudy fasterQuestion 13 of 23 Loading... 14.

Which is more reactive: silver, gold, copper or iron?coppersilvergoldironQuestion 15 of 23 Loading... 16. Are metal oxides acidic or basic?NeutralBasicAcidicDepends on conditionsQuestion 16 of 23 Loading... 17. 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 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 sodiumSodium 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 sodiumQuestion 17 of 23 Loading... 18. 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 the same number of protonsElements 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 different numbers of electrons in their outer shellQuestion 18 of 23 Loading... 19. Suggest how the reactivity of fluorine compares to chlorineFluorine is more reactive than chlorine as it is higher in the group.Fluorine is less reactive than chlorine as it is more stable as an elementFluorine is more reactive than chlorine because it has a lower boiling pointFluorine is less reactive than chlorine because it is more volatileQuestion 19 of 23 Loading... 20. What colour and state is iodine at room temperature?brown gasred-brown liquiddark grey solidyellow-brown liquidQuestion 20 of 23 Loading... 21. 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 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 metalQuestion 21 of 23 Loading... 22. Describe the conditions under which iron rustscarbon dioxide onlyoxygen onlywater and carbon dioxideoxygen and waterQuestion 22 of 23 Loading... 23. 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?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. Lithium would give off a orange flame, showing it is most reactive.Sodium would bubble the least vigorously, showing it is least reactive. Potassium would give off a orange flame, showing it is most reactive.Lithium would bubble the least vigorously, showing it is least reactive.
