Question: The minimum energy required to excite a hydrogen atom from its ground state is [EAMCET (Engg.) 1995; MP PMT 1997; CPMT 1999; DCE 1999]
Options:
A) 13.6 eV
B) $ -13.6\ eV $
C) 3.4eV
D) 10.2 eV
Show Answer
Answer:
Correct Answer: D
Solution:
Minimum energy required to excite from ground state $ =13.6[ \frac{1}{1^{2}}-\frac{1}{2^{2}} ]=10.2\ eV $
