As far as the elements are placed in periodic table, the more violently they reacts to each other. The alkali metals (Li, Na, K, Rb, Cs, and Fr) are the most reactive metals in the periodic table - they all react vigorously or even explosively with cold water, resulting in the displacement of hydrogen. (Total 1 mark) 6. Relevance. Looking for something else? As they are in the same group, they have similar chemical properties and will react with substances (including water) in a similar way. Rubidium is an element in the same group of the periodic table as lithium and sodium. Because Li is the strongest reducing agent of the alkali metals, it reacts most quickly with water of the alkali metals. Which element in the group is the most metallic in character? It is likely to be a metal which has a A. high melting point and reacts slowly with water. Feb 5, 2014 . Pieces of it explode in water with increasing intensity going down the group. In each case, a solution of the metal hydroxide is produced together with hydrogen gas. It is primarily used as a hardening agent in alloys, most notably beryllium copper. Find more answers. It is likely to be a metal which has a A. high melting point and reacts slowly with water. General. HF. Sodium (N a) C. Potassium (K) D. Rubidium (R b) Answer . Subsequently, one may also ask, which element in group 2 is most metallic in character? The group 1 elements react with oxygen from the air to make metal oxides.
