WebWhen metals react with other substances, the metal atoms lose electrons to form positive ions. The reactivity series of metals is a chart showing metals in order of decreasing reactivity.... WebAug 14, 2024 · The alkali metals are very reactive, readily losing 1 electron to form an ion with a 1+ charge: \[M \rightarrow M^+ + e- \nonumber \] ... The alkaline earth metals are therefore less reactive than the alkali metals (Be and Mg are the least reactive of the alkaline earth metals). Several physical properties of these elements are compared in ...
