Group 1 – The Alkali Metals The group 1 elements are known as the alkali metals. They’re very reactive which means they are rarely found in their elemental form. Francium is so reactive that there is only around 30g found in the Earth’s crust at any given time! Learning Objective 1 (Expected Progress): Understand the different command words used and their meanings. Recap over all the biology content covered in cycle 2 Learning Objective 2 (Above Expected Progress): Understand how to answer 6-mark questions effectively. Group 1 Reactivity Due to their reactivity, the alkali metals are stored in oil. This prevents them from reacting with oxygen in the air. Alkali metals are unusual metals! Most metals are very hard and dense, however, group 1 metals are soft and generally float on water. The elements in group 1 also react with water and form alkaline compounds. This is why they are called alkali metals. Learning Objective 1 (Expected Progress): Understand the different command words used and their meanings. Recap over all the biology content covered in cycle 2 Learning Objective 2 (Above Expected Progress): Understand how to answer 6-mark questions effectively. Group 1 + water When group 1 metals react with water, they follow the general equation: metal + water → metal hydroxide + hydrogen So, for lithium’s reaction with water, the equation would be: lithium + water → lithium hydroxide + hydrogen Complete the equations for the reactions between sodium and potassium with water.

Identifying a displacement reactions Displacement reactions are easily seen when a salt of the less reactive metal is in the solution. During the reaction: ▪ the more reactive metal gradually disappears as it forms a solution. ▪ the less reactive metal coats the surface of the more reactive metal.
