The alkali metals react with oxygen to form several different compounds: suboxides, oxides, peroxides, superoxides, and ozonides. They all react violently with Sep 2, 2014 — All of the alkali metals are found naturally in nature, but not in their pure forms. Most combine with oxygen and silica to form minerals in the The Alkali Metals form Group 1 of The Periodic Table, and called so because they form oxides and hydroxides that dissolve in water to give alkaline solutions.

The alkali metals are so called because reaction with water forms alkalies (i.e., strong bases capable of neutralizing acids). Sodium and potassium are the sixth This shows that the reactivity of the alkali metals increases as you go down group 1. In a reaction, this electron is lost and the alkali metal forms a +1 ion.Group I of the Periodic Table is composed of highly reactive metals. Alkali metals tend to lose one electron and form ions with a single positive charge. Alkali metals are highly reactive at standard temperature and pressure and readily lose their outermost electron to form cations with charge +1. All the alkali metals are highly reactive and are never found in elemental forms in nature. Because of this, they are usually stored in mineral oil or kerosene
