Alkali Metal Reactivity | Chemdemos

The reaction of alkali metals with water is represented by the following equation: 2 M (s or l) + 2 H2 O (l) --> 2 M (OH)2(aq) + H 2(g) Where M is the alkali metal. The heat given off by this reaction immediately melts the sodium and potassium and is frequently sufficient to ignite the hydrogen gas produced: and to ignite the metals themselves

Metallic and Non-Metallic Character: Periodic …

Metallic Character of a Metal. Metallic character refers to the level of reactivity of a metal. Metals tend to lose electrons in chemical reactions, as indied by their low ionization energies. Within a compound, metal atoms have a relatively low attraction for electrons. This is indied by their low electronegativities.
