Reaction of Group 1 Elements with Water, Oxygen Gas

Group 1 elements have one electron in the valence shell. In a chemical reaction, these atoms donate
one electron and form an ion with the +1 charge.
Lithium, sodium and potassium have the same chemical properties
but different reactivity.
When alkali metals react with water, an alkaline hydroxide solution
and hydrogen gas are formed. For example, the reaction of lithium with
water will produce lithium hydroxide and hydrogen gas.
When alkali metals burn in oxygen gas, a white solid that is metal oxide will be formed.
For example, the reaction of lithium with oxygen gas will produce lithium oxide
