Why Do Alkali Metals and Halogens React
Halogens are so reactive because they have 7 valence electrons and are very close to having a complete shell of 8 electrons. The Halogens - Reactions with Metals. Chemical Reaction Images Chemical Reactions Chemistry Lessons Science Chemistry Law Of Multiple Proportions Why does Group 7 get less reactive. . Reactivity decreases down the group. The noble gases have filled valence shells as they occur in nature. 2K H 2 SO 4 K 2 SO 4 H 2. Exposing an alkali metal to a halogen will cause an extremely exothermic reaction that results in an ionic salt. Because they have only one valence electron group 1 elements are highly reactive. Group 1 metals - see the reaction with alkali metals. In this way why is Group One called alkali metals. It is this electrostatic attraction that forms ionic bonds in metal halides and other ionic compounds. The halogens are reactive non-metals. The group 1 of the pe...
