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
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
