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 collection of elements with the same number of electron shellsA Group is a horizontal row of elementsQuestion 10 of 23 Loading... 11. Suggest how the reactivity of astatine compares to that of iodine. Explain your answer.Astatine is more reactive because group 7 elements get more reactive with decreasing atomic number.Astatine is more reactive because group 7 elements get less reactive with decreasing atomic number.Astatine is less reactive because group 7 elements get less reactive with increasing atomic number.Astatine is more reactive because group 7 elements get more reactive with increasing atomic number.Question 11 of 23 Loading... 12. Write the word equation to represent the reaction between sulfuric acid and magnesiumsulfuric acid + magnesium → magnesium sulfide + hydrogensulfuric acid + magnesium → magnesium sulfate + hydrogensulfuric acid + magnesium → magnesium sulfate + watersulfuric acid + magnesium → magnesium sulfide + waterQuestion 12 of 23 Loading... 13. 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 2,1. 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 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 13 of 23 Loading... 14. On the Periodic Table what is the meaning of the word Period? What does that tell us about the electron configuration of the atom?Same electronic configurationsame number of electron shellssame number of electrons in the outer shellSame number of electrons in the inner shellQuestion 14 of 23 Loading... 15. 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 reactivePotassium 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. Lithium would oxidise the slowest, showing it is least reactive.Question 15 of 23 Loading... 16.

Explain, in terms of the arrangement of electrons in its atoms, why neon is very unreactiveNeon is a noble gasNeon 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 electronsNeon has an even number of electrons so it does not need to form bondsQuestion 20 of 23 Loading... 21. What is the colour and physical state of chlorine at room temperature?green liquidGreen gasyellow gasyellow liquidQuestion 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 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.
