It is also a basic building block of table salt (a molecule of which consists of one atom of sodium and one of chlorine: NaCl). Metal starts moving over the surface of water making a hissing sound. To me, it seems like a metal would need to be more reactive to be able to react with hot water since HCl is a very strong acid and so should theoretically be able to react with more metals, but I am not so sure. One notable reaction within this group is aluminum's (Al) reaction with water. Explain the reactions of different metals with hot water, cold water and steam.

My main research advisor refuses to give me a letter (to help for apply US physics program). Thanks for contributing an answer to Chemistry Stack Exchange! The reason for using cold water rather than hot water for the reactions of alkali metals is that alkali metals are already reactive enough at room temperature. When water touches alkali metals the reaction produces hydrogen gas and a strong alkaline solution, also known as a base. Starting from sodium, they react explosively to water, as hydrogen gas is produced in the process.
