As per Bohr model, the minimum energy (in eV) required to remove and electron from the ground state of double ionized Li atom \((Z=3)\) is
- A \(1.51\)
- B \(13.6\)
- C \(40.8\)
- D \(122.4\)
Answer & Solution
Correct Answer
(D) \(122.4\)
Step-by-step Solution
Detailed explanation
\(E=-2^{2} \times 13.6 \mathrm{eV} \)
\(E =-9 \times 1.6 \mathrm{eV} \)
\( E =-122.4 \mathrm{eV}\)
So, ionization energy is \(+122.4 \mathrm{eV}\)
\(E =-9 \times 1.6 \mathrm{eV} \)
\( E =-122.4 \mathrm{eV}\)
So, ionization energy is \(+122.4 \mathrm{eV}\)
