Alkali metals have only +1 ionic charge in their compounds when alkaline earth metals have +2 ionic charges in their compounds. Red. The alkali metals, found in group 1 of the periodic table (formerly known as group IA), are very reactive metals that do not occur freely in nature. Thus, this electron can easily escape the positive pull of the nucleus to be donated to other elements, resulting in a reaction. Watch the recordings here on Youtube! This demonstration is good for illustrating the chemical characteristics of metals, reactivity of Group 1A metals trends, Ionization Energy Trend. Most alkali metals have many different applications, such as rubidium and caesium atomic clocks, sodium-vapor lamps, and table salt. Contact: Randy Sullivan, smrandy@uoregon.edu. Thus, this electron can easily escape the positive pull of the nucleus to be donated to other elements, resulting in a reaction. These metals have different characteristics from the common metal. Sodium reacts more quickly, generating enough heat to melt itself and to occasionally ignite the hydrogen gas, producing a yellow-orange flame characteristic of sodium. Be sure to place the wire gauze over the mouth of the cylinders immediately to avoid spattering. Because of their high reactivity, the alkaline earths are not found free in nature. All alkali metals have one valence electron. Going down the Group 1A elements from Li to K, the outermost electron is further away from the nucleus and the overall net force of attraction between the protons in the nucleus and the outermost electron decreases. As a result, in the laboratory they are stored under mineral oil to minimise reaction with oxygen or water vapour in air.
