Atoms And Nuclei Question 39
Question: An electron in the n = 1 orbit of hydrogen atom is bound by 13.6 eV. If a hydrogen atom is in the n = 3 state, how much energy is required to ionize it [MP PMT 1995]
Options:
A) 13.6 eV
B) 4.53 eV
C) 3.4 eV
D) 1.51 eV
Show Answer
Answer:
Correct Answer: D
Solution:
Required energy $ E_{3}=\frac{+13.6}{3^{2}}=1.51eV $
