Potassium
Three metals that react with cold water are sodium, potassium, and lithium. These alkali metals react vigorously with water, producing hydrogen gas and corresponding hydroxides. Sodium reacts to form sodium hydroxide, while potassium reacts more violently, leading to the production of potassium hydroxide. Lithium reacts more slowly compared to the other two but still produces lithium hydroxide and hydrogen when in contact with cold water.
Lithium, sodium, potassium. rubidium, cesium, francium, calcium, strontium, barium and radium all react with varying degree of vigor with water to produce hydrogen gas. Other metals also will but not as vigorously.

Potassium and lithium.
The two most common alkali metals are sodium and potassium. They are found in many compounds and minerals, and are essential for various biological processes in living organisms.
Lithium, sodium, and potassium react vigorously with water to form hydroxides and release hydrogen gas. The reactivity increases as you go down the group from lithium to potassium, with potassium being the most reactive.
Iron is the odd one out because it is a transition metal, while lithium, potassium, and sodium are alkali metals.

Color is determined by the respective cation: Potassium - lilac Sodium - yellow Lithium - red
Iron is the odd one out because it is a transition metal, while lithium, sodium, and potassium are alkali metals.
The element lithium has the symbol Li.The element sodium has the symbol Na (from natrium in Latin and Νάτριο in Greek)The element potassium has the symbol K (from kalium, Latin).
