Alkali Metals: Alkali metals are elements of group 1.They are called alkali metals because the hydroxides they form on reaction with water, is highly alkaline in nature. The elements listed below constitute group 1 elements and are collectively considered as alkali metals. ...
What happens when alkali metals react with molecular hydrogen? Describe some uses for magnesium and its compounds. What will happen if 100g of NaCl is placed in 200mL of water at 70^oC? Magnesium combines with oxygen to form a brittle white solid. Is this a chemical or physical change?
Step-by-Step Solution:1. Understanding the Reactivity Series: - The reactivity series is a list of metals arranged in order of decreasing reactivity. The metals at the top of this series are highly reactive.
