Which of the following has the least ionization potential?
Correct answer: B. Li
- A. He
- B. Li
- C. Zn
- D. N
Explanation
Lithium is an alkali metal, and alkali metals have very low ionization potentials due to their single valence electron and large atomic size. Lithium requires the least amount of energy to remove its valence electron.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
