Why Do Alkali Metals and Halogens React
What state of matter is sodium. To have very good reactivity for metals ease. Periodic Table Alkali Metals Group 1a Alkaline Metals Group 2a Transition Metals Group B Metalloids 7 Purple Ele Periodic Table Transition Metal Alkali Metal - 4K O2 2K2O. . When going down the group atomic radius of metal increases. 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. The halogens react with metals to produce salts the word halogen means salt former. Observe the reaction of lithium sodium and potassium reaction with water. Oxide layer forms quicker as we go down the group. React with oxygen and water. Hence in the alkali metals and halogens the most reactivity combination would be ceasium fluoride. Since the alkali metals and halogens comes under 1st group and 17th group they have one electron and seven electrons in the oute...
