Reactivity of metals towards oxygen
WebChemical properties. Since the alkali metals are the most electropositive (the least electronegative) of elements, they react with a great variety of nonmetals. In its chemical reactivity, lithium more closely resembles Group 2 (IIa) of the periodic table than it does the other metals of its own group.It is less reactive than the other alkali metals with water, … WebWhen metals react with oxygen, metal oxides are formed. The speed of the reaction depends on the reactivity of the metal. Watch this video for a practical demonstration of reacting...
