The document outlines an assignment on alkali and alkaline earth metals. It asks the student to define alkali metals, provide examples of alkali and alkaline earth metals, describe how reactivity changes down the alkali metal group, and write balanced chemical equations for reactions involving sodium, calcium, potassium, and magnesium.
