The tendency of alkali metals to act as strong reducing agents is evident from the fact that these metals can liberate H2 from H2 O and acids. 2M+2H2O-----------------2MOH+H2 2M+2HCl------------------2MCl+H2
We have already seen that Li atom loses its ns1 electron with great difficulty while Cs atom should have maximum reducing power among the alkali metals . In other words ,we can also say Li -atom ,because of its maximum ionisation energy, should have minimum reducing power and Cs atom ,because of its minimum ionisation energy ,should have maximum reducing power .
The high valves of oxidation potential show that alkali metals can lose their ns1 electron quite readily and hence have a strong tendency to act as reducing agents.

What is the order or reducing property of alkali metals?
the order of reducing capacities is: Na<K-Rb<Cs<Li
What are physical properties for alkali metals?
Alkali metals are powerful reducing agents, they give up one electron easily. They are extremely reactive.
How many electrons occupy the highest energy sublevel of alkali metals?
90
Alkali metals cannot be used in voltaic cells?
Lithium is an alkali metal and is used in the highest energy capacity cells made.
Which properties of alkali metals unusual metals?
Alkali metal forms Alkali while metals form bases.
What makes alkali metals such good reducing agents?
Alkali metals have one valence electrons. If they will lose these electrons they will attain the electronic configuration of the nearest noble gas and hence form stable cations. Hence alkali metals are good reducing agents (tend to give off electrons).

Why alkali metals are good reducing agent?
Alkali metal have a strong tendency to lose electrons and act as good reducing agents. The reducing character increases from sodium to caesium. However lithium is the strongest reducing agent.ReasonThe alkali metals have low value of ionization energy which decreases down the group and so can easily lose their valence electron and thus act as good reducing agents.

Lithium is better reducing agent than cesium in aqueous solution?
, the alkali metals are powerful reducing agents. Lithium in aqueous solution is as strong a reducing agent as Caesium. This is probably due to high hydration energy of small lithium ion, which compensates for high ionisation energy. The hydration energy of alkali metal ions follows the order: Li+ > Na+ > K+ > Rb+ > Cs+ . Due to extensive hydration, Li+ ion has the highest hydration energy, as a result of which reduction potential of Li is higher than other alkali metals. Thus most powerful reducing agent in solution is lithium.
