Please help 1. The most chemically reactive metal elements are soft. These metals are so reactive that they react spontaneously with water and/or substances in the atmosphere and therefore must be stored under oil. Where is this family (group) of metals located in the periodic table? 2. Based on for Li, Na and K and the relationship between reactivity and positions of elements in the periodic table, what would you predict for the reactivity of Rb? 3. Looking at the...
