Question

Potassium is more reactive than sodium.Explain with the help of ionization energy.

Answer 1

The atomic radius of potassium is greater than that of sodium. Therefore, the single valence electron that exists for all alkali metals is located farther from the nucleus for potassium than sodium. This results in less energy required to remove that valence electron from potassium than from sodium, leading to increased reactivity...............
Sorry if I am wrong.....but i Think its correct
