The alkali metals are called good reducing agents. this implies that__: [a] they easily capture electrons [b] they are not stable at room temperature [c] they easily lose electrons [d] they don't act with dilute acids
Answers
Concept introduction
The electron donor, or reducing agent, is a substance that is normally in one of its lowest potential oxidation states. Because it loses electrons in the redox process, a reducing agent becomes oxidized. The earth metals, formic acid, and sulfite substances are a few examples of reducing agents.
Given
The alkali metals are called good reducing agents.
Find
Why alkali metals are said to be good reducing agent.
Solution
Reducing agents are those elements of compounds which reduce another compounds and oxidize itself. Now elements oxidize by loosing electrons and elements reduce by gaining electrons. Hence alkali metals loose electrons to get oxidized and reduce other elements.
Hence, [c] they easily lose electrons.

Answer:
c) They easily lose electrons.
Explanation:
An oxidizing agent is the one that causes the oxidation of other species by making it lose electrons. Thus, an oxidizing agent itself got reduced.
Similarly, a reducing agent is the one that causes the reduction of other species by donating electrons to them. Thus, a reducing agent itself got oxidized.
Alkali metals are group 1 elements and include Li, Na, K, Rb, Cs, and Fr. These all metals have one electron in their valence shell and they are good reducing agents. As good reducing agents are capable to donate electrons easily, this means that they are ready to donate their valence electrons.
Hence, the correct option is c) They easily lose electrons.
