Reactivity Series of Metals - Get the Chart, Significance …
In the reactivity series, as we move from bottom to top, the reactivity of metals increases. Metals present at the top of the series can lose electrons more readily to form positive ions and corrode or tarnish more readily. They require more energy to be separated from their ores, and become stronger reducing agents, while metals present at the bottom of the series are good oxidizing agent.

Learners need to be made aware that compounds may occur as two types of structures, namely molecules and lattices: When a compound is made up entirely of non-metals (CO 2, H 2 O, or NH 3, for example), the smallest unit of that compound will be a molecule.
Despite significant decreases in exposure due to technological improvements and reduced usage in some products and industrial processes, these metals continue to pose health and environmental risks. For example, blood lead levels in U.S. children have declined by 90% since the mid-1970s from the elimination of lead in gasoline and paint.

The alkali metals are so reactive that they are never found in nature in elemental form. Although some of their ores are abundant, isolating them from their ores is somewhat difficult. For these reasons, the group 1 elements were unknown until the early 19th century, when Sir Humphry Davy first prepared sodium (Na) and potassium (K) by passing an electric current through molten alkalis.
