Metal Reactivity & Halogens quiz Loading... 1. 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 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. Lithium would not burn at all showing it is least reactiveSodium would oxidise the most quickly, showing it is most reactive.

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 different numbers of electrons in their outer shellElements 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.)Question 2 of 23 Loading... 3.

An experiment investigates which of metals X and Z is more reactive. The result is X + ZSO₄ → X + ZSO₄. Which metal is more reactive?XSO₄ZSO₄ZXQuestion 7 of 23 Loading... 8. Which is more reactive: sodium, zinc, magnesium or aluminium?aluminiumzincmagnesiumsodiumQuestion 8 of 23 Loading... 9. Write the word equation to represent the reaction between hydrochloric acid and calciumhydrochloric acid + calcium → calcium chloride + hydrogenhydrochloric acid + calcium → calcium hydrochloride + waterhydrochloric acid + calcium → calcium hydrochloridehydrochloric acid + calcium → calcium chloride + waterQuestion 9 of 23 Loading... 10. Explain, by referring to the electronic configurations, why fluorine is more reactive than chlorineFluorine has the electronic configuration 2,7 and chlorine has 2,8,7. 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 2,7 and chlorine has 2,8,7. An extra outer electron is gained more easily by chlorine.

Where are the transition metals on the Periodic Table?Scattered across itIn the middleLeft hand colunmTop left cornerQuestion 11 of 23 Loading... 12. 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 inner shellsame number of electrons in the outer shellSame number of electron shellsSame electronic configurationQuestion 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.

On the Periodic table what is the meaning of the word Group?A Group is a vertical column of similar elementsA Group is a collection of similar elementsA Group is a horizontal row of elementsA Group is collection of elements with the same number of electron shellsQuestion 15 of 23 Loading... 16. Do metals other than iron rust?Yes. Metal oxides that form at room temperature and pressure with only water and oxygen can be called rustYes. any oxide can be called rustYes. Any metal salt can be called rustNo. The term rust is only applied to ironQuestion 16 of 23 Loading... 17. What is sacrificial protection?Sacrificial 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 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 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 close to a less reactive metal. Only the more reactive metal corrodes, so protecting the less reactive metalQuestion 17 of 23 Loading... 18.

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.
