Question 62
1 mark · Easy
Answer and see the solution →State whether chlorine is a metal or a non-metal, based on its position in the periodic table.
Question 63
3 marks · Easy
Answer and see the solution →This question is about group trends in the periodic table.
(a)[1 mark]State how many electrons a typical Group 7 element has in its outer shell.
(b)[2 marks]Explain why the elements fluorine and bromine have similar chemical properties.
Question 64
2 marks · Easy
Answer and see the solution →An oxide of aluminium (Al) reacts with hydrochloric acid to produce 27 grams of aluminium chloride. Given the information below, use the periodic table and your knowledge of metals and oxides to calculate the number of moles of aluminium chloride formed. (Al = 27, Cl = 35.5)
