In this chapter, we will be learning about the reactivity of metals. We will start by exploring the variety of minerals found in the Earth's crust and identifying the elements present in natural compounds.
Next, we will construct a reactivity series of metals based on their reactions with oxygen and write the word equations for these reactions. We will also determine the position of carbon and hydrogen in the reactivity series.
Lastly, we will learn about the extraction of metals from their ores and discuss the impact of unplanned mining activities on life on Earth. We will use illustrations to understand the extraction process and brainstorm ideas to solve problems caused by mining.
• Explain with examples minerals that are found in the Earth’s crust
• Identify elements found in natural compounds
