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 $
