JEE Mains · Physics · STD 12 - 12. atoms
Radiation coming from transition \(n = 2\) to \(n = 1\) of hydrogen atoms fall of \(He^+\) ions in \(n = 1\) and \(n = 2\) states. The possible. Transition of helium ions as they absorb energy from the radiation is
- A \(n = 2 \to n = 4\)
- B \(n = 2 \to n = 5\)
- C \(n = 2 \to n = 3\)
- D \(n = 1 \to n = 4\)
Answer & Solution
Correct Answer
(B) \(n = 2 \to n = 5\)
Step-by-step Solution
Detailed explanation
Energy released for tension \(\mathrm{n}=2\) to \(\mathrm{n}=1\) of hydrogen atom \(E=13.6 Z^{2}\left(\frac{1}{n_{1}^{2}}-\frac{1}{n_{2}^{2}}\right)\) \(z=1, n_{1}=1, n_{2}=2\) \(E=13.6 \times 1 \times\left(\frac{1}{1^{2}}-\frac{1}{2^{2}}\right)\)…
