Atoms And Nuclei Question 13
Question: The ionization potential for second He electron is
Options:
A) 13.6 eV
B) 27.2 eV
C) 54.4 eV
D) 100 eV
Show Answer
Answer:
Correct Answer: C
Solution:
For the ionization of second He electron. $ H{{e}^{+}} $ will act as hydrogen like atom. Hence ionization potential $ =Z^{2}\times 13.6,volt={{(2)}^{2}}\times 13.6=54.4,V $
