When the alkali metals react with the different halogens (Group 7 of the periodic table), the group of compounds formed are known as the alkali metals halides. Due to the fact that there are a ...

They react with water to produce an alkaline metal hydroxide solution and hydrogen. Reactivity increases down the group. Group 7 - the halogens - Edexcel The group 7 elements are all reactive non ...

Although it is technically a non-metal, it exhibits some ... and astatine (At). The term halogen means "salt-producing." When these elements react with metals, they produce a wide variety of ...

and oxygen evolution reaction (OER) typically require precious metals as electrocatalysts. This limitation has prompted researchers to focus on developing effective non-precious metal catalysts to ...
