2 1. statine is an element in Group VII of the Periodic Table. It has only ever been produced in very small amounts. What is the best description of its likely properties? 2. Which statement describes the trends going down group VII of the Periodic Table? The boiling point and melting point both decrease. The boiling point and melting point both increase. The boiling point decreases but the melting point increases. The boiling point increases but the melting point decreases. 3. The table compares the properties of Group I elements with those of transition elements. Which entry in the table is correct? 2

3 4. The diagram shows the positions of elements P, Q, R, S and T in the Periodic Table. These letters are not the chemical symbols for the elements. S T P Q R Which statement about the properties of these elements is correct? P reacts more vigorously with water than does Q. P, Q and R are all metals. T exists as diatomic molecules. T is more reactive than S. 5. Which is not a property of Group I metals? They are soft and can be cut with a knife. They corrode rapidly when exposed to oxygen in the air. They produce an acidic solution when they react with water. They react rapidly with water producing hydrogen gas. 6. Solutions of a halogen and a sodium halide are mixed. Which mixture darkens in colour because a reaction occurs? bromine and sodium chloride bromine and sodium fluoride chlorine and sodium fluoride chlorine and sodium iodide 3

4 7. The table shows some properties of two elements in Group VII of the Periodic Table. Which properties is fluorine likely to have? 8. X is a monatomic gas. gas X Which statement about X is correct? X burns in air. X is coloured. X is unreactive. X will displace iodine from potassium iodide. 4

5 9. The diagram shows a section of the Periodic Table. I II III IV V VI VII 0 V W X Y Z Which elements will conduct electricity at room temperature? V, W and X V, Y and W W, X and Z Y and Z 10. The equation shows the reaction between a halogen and aqueous bromide ions. X 2 + 2r (aq) 2X (aq) + r Which words correctly complete gaps 1, 2 and 3? 5

6 11 The diagram shows an outline of the Periodic Table. U V W X Y Which of the elements U, V, W, X and Y would react together in the ratio of 1 : 1? U and X U and Y V and Y W and X 12 The element rubidium, Rb, is immediately below potassium in the Periodic Table. It reacts with bromine to form the compound rubidium bromide. Which descriptions of this compound are correct? type of bond formula colour covalent Rbr brown covalent Rbr 2 white ionic Rbr white ionic Rbr 2 brown 6

7 13 Element X is in Group VII of the Periodic Table. It reacts with aqueous potassium bromide as shown. Which statements about X are correct? X 2 + 2Kr 2KX + r 2 relative atomic mass greater than that of bromine greater than that of bromine less than that of bromine less than that of bromine reactivity less reactive than bromine more reactive than bromine less reactive than bromine more reactive than bromine 14 The diagram shows a section of the Periodic Table. Which element is described below? colourless, unreactive gas that is denser than air. 7

8 15. Element X is below iodine in the Periodic Table. Which row correctly shows the physical state of element X at room temperature and its reactivity compared with that of iodine? physical state of element X at room temperature gas solid gas solid reactivity compared with that of iodine less reactive less reactive more reactive more reactive 8

9 16. The diagram shows an outline of part of the Periodic Table. X Y Z Which statement about elements X, Y and Z is not correct? ll are metals. ll conduct electricity. ll form coloured compounds. ll react with oxygen. 17. The diagrams show the labels of four bottles. Which label is not correct? romine r 2 Iodine I 2 Potassium K Sodium Na Harmful liquid. o not spill. anger void breathing vapour from the solid. anger Store under water. anger Store under oil. 9

10 18. Fluorine is at the top of Group VII in the Periodic Table. Which row shows the properties of fluorine? colour state at room temperature reaction with aqueous potassium iodide brown gas brown liquid yellow gas yellow liquid no reaction iodine displaced iodine displaced no reaction 19. Group I metals are also known as the lkali Metals. Which statement about the metals in Group I is not correct? In their reactions they lose electrons. Their atoms all have one electron in their outer shell. They form +1 ions in their reactions with non-metals. They form covalent compounds by sharing electrons Which element will be less reactive than the other members of its group in the Periodic Table? astatine caesium fluorine rubidium 21. romine is in Group VII on the Periodic Table. Which describes the appearance of bromine at room temperature? grey solid purple fumes red-brown liquid yellow gas 10
