Alkali metals are powerful reducing agents because
Options
- Athey are metals
- Bthey are monovalent
- Ctheir ionic radii are large
- Dtheir ionisation energies are low
Correct answer
D. their ionisation energies are low
Step-by-step solution
Alkali metals have only one valence electron in their outermost shell. They loose one valence electron easily due to low ionisation enthalpy and get oxidised to reduces other compounds.
