Atoms And Nuclei Question 21
Question: The ionisation potential of hydrogen atom is 13.6 volt. The energy required to remove an electron in the n = 2 state of the hydrogen atom is [NCERT 1983; MP PET 2005]
Options:
A) 27.2 eV
B) 13.6eV
C) 6.8eV
D) 3.4eV
Show Answer
Answer:
Correct Answer: D
Solution:
Energy required to remove electron in the n = 2 state $ =+\frac{13.6}{{{(2)}^{2}}}=+3.4,eV $
