The energy required to remove the electron from a singly ionized Helium atom is \(2.2\, times\) the energy required to remove an electron from Helium atom . The total energy required to ionize the Helium atom completely is......\(eV\)
- A \(20\)
- B \(79\)
- C \(109\)
- D \(34\)
Answer & Solution
Correct Answer
(B) \(79\)
Step-by-step Solution
Detailed explanation
Energy required to remove e - from singly ionized helium atom \({ = \frac{{(13.6){Z^2}}}{{{1^2}}} = 54.4\,{\text{eV}}}\) \((\because Z=2)\) Energy required to remove \(e^-\) from helium atom \(=x\,eV\) According to question,…
