Question

Which ionization process requires the most energy? Explain?

A) W(g) → W+(g) + e-

B) W+(g) → W2+(g) + e-

C) W2+(g) → W3+(g) + e-

D) W3+(g) → W4+(g) + e-

 

Answer 1

Answer:

Our Answer would be Choice - D) i.e. W³⁺⁽g) W⁴⁺(g) + e^-   (i.e. the fourth ionization energy)

Explanation:

As we know, the first ionization energy is always greater then the second ionization energy (i.e. energy required for taking away one electron from an atom already having charge of +1 ), and similarly, each succeeding ionization energy would be larger that the preceding ionization energy and this holds true, always and under all circumstances.

Therefore...we can surely say... that the Ionization Energy required for Choice - D...(i.e. the fourth ionization energy) will be the largest energy, among the given Ionization Processes (i.e... first ionization energy to third ionization energy (-ies).
