WebExplaining reactivity. The Group 1 elements have similar properties because of the electronic structure of their atoms. – they all have one electron. in their outer shell. WebDue to its high degree of reactivity, pure potassium is rarely used in its elemental /metallic form. It is used as a powerful reducing agent in organic chemistry. Potassium/Sodium alloys are It used as a heat exchange medium . The heat in the potassium warms water and makes it hot enough to boil. Then water is changed into steam, which is used ...

WebSummary. The elements Li, Na, and K belong to group IA of the periodic table and are part of the group known as the alkali metals. Ammonium salts inhibit radiation of the alkali metals; consequently most procedures for flame photometer determinations call for destroying the NH 4 + salts. For Li analysis, dilute to a total volume of 50 ml rather ... WebPotassium has considerably less use than sodium as a free metal. Potassium salts, however, are consumed in considerable tonnages in the manufacture of fertilizers. …
