- Magnesium: Reacts slowly with cold water, but can react more significantly with steam.

- Aluminium: Generally does not react with cold water due to its protective oxide layer.

- Zinc: Reacts with hot water or steam, but very little to no reaction with cold water.

- Potassium: Reacts violently with cold water, producing heat and hydrogen gas, and often ignites the hydrogen.
