Question 11
5 marks · Hard
Answer and see the solution →The periodic table below shows four elements, X, Y, Z, and W.
Positions of elements in the periodic table and their oxide formulae. Element Group Period Formula of oxide X 1 3 XO Y 7 3 Y2O7 Z 2 2 ZO W 6 3 WO3 (a)[2 marks]Which two elements in the table are metals? Give a reason for your choice.
(b)[2 marks]Which one element forms an acidic oxide? Explain your answer.
(c)[1 mark]State one property (other than oxide character) that most metals have which non-metals do not.
Question 12
2 marks · Hard
Answer and see the solution →Give a reason why elements in Group 0 (the noble gases) do not easily form compounds. Your answer should refer to their electronic structure.
Question 13
2 marks · Hard
Answer and see the solution →State the acid–base character of the oxides formed by sodium and chlorine. Use one phrase each.
Question 14
5 marks · Hard
Answer and see the solution →The elements magnesium and sulfur have very different properties. Answer the following questions about them.
(a)[2 marks]State two typical physical properties that distinguish metals from non-metals.
(b)[2 marks]For each of the properties stated in part (a), describe how magnesium and sulfur show these properties.
(c)[1 mark]Name one exception to a typical physical property of metals or non-metals and give a specific example.
Question 15
2 marks · Hard
Answer and see the solution →Hydrogen is found in Group 1 of the Periodic Table but is not a typical metal. Use examples to describe one way in which its electrical conductivity is different from most metals.
Question 16
7 marks · Hard
Answer and see the solution →This question is about electronic configurations and differences in electrical conductivity between metals and non-metals.
(a)[2 marks]Draw a diagram to show the electronic configuration of the element with atomic number 6. Use shells and electrons as dots or crosses.
(b)[2 marks]Element X has the electronic configuration 2,8,1. Identify whether X is a metal or a non-metal. Explain your answer based on its electronic configuration.
(c)[2 marks]Describe how the electrical conductivity of sodium compares to that of sulfur. Give a reason for your answer linked to their electronic structures.
(d)[1 mark]Name one exception among non-metals that can conduct electricity and explain why it is an exception.
Question 17
8 marks · Hard
Answer and see the solution →This question is about the arrangement of electrons in atoms and the physical properties of metals and non-metals.
(a)[2 marks]Draw a diagram to show the electronic configuration of an atom of nitrogen (atomic number 7) using shells and dots or crosses to represent electrons.
(b)The atomic number of magnesium is 12, and the atomic number of oxygen is 8. Both elements are found in the same period of the Periodic Table.
(i)[1 mark]State whether magnesium is a metal or a non-metal.
(ii)[1 mark]State whether oxygen is a metal or a non-metal.
(c)[2 marks]Describe two physical properties that can be used to distinguish a typical metal such as magnesium from a typical non-metal such as oxygen.
(d)[2 marks]Name one exception to the typical properties of metals or non-metals, as described in this question.
