Question

Which of the following electronic transitions requires that the greatest quantity of energy be absorbed by a hydrogen atom?

• A. n = 1 to n = 2
• B. n = 2 to n = 4
• C. n= 3ton= 6
• D. n = 1 to n = $ \infty $

Answer 1

Answer: (D)

$ \Delta \Epsilon =cons\tan t $ $ \left[ \frac{1}{{{n}_{1}}^{2}}-\frac{1}{n_{2}^{2}} \right], $ Transition with maximum valu e of $ {{n}_{2}} $ and least value of $ {{n}_{1}} $ will absorb greatest quantity of energy $ (n=1\,to\,n=\infty ) $
