Question 6
3 marks · Easy
Answer and see the solution →(a)[3 marks]Copper is a useful metal in electrical wiring and making utensils. State and explain two properties of copper that are important for these uses.
Question 7
2 marks · Easy
Answer and see the solution →Each atom of lithium in solid lithium metal loses one electron to become a Li ion. In a piece of lithium metal containing lithium atoms, calculate the total number of delocalised electrons present.
Question 8
2 marks · Easy
Answer and see the solution →Draw a simple 2D diagram to represent the metallic lattice structure in a sample of rubidium metal. Clearly show and label the positive metal ions and sea of delocalised electrons.
Question 9
