Question
In a sample of hydrogen atoms, what is the maximum number of emission lines obtained when the excited electrons in $n = 5$ drop to the ground state?
Answer: B
💡 Solution & Explanation
The maximum number of spectral lines emitted when electrons drop from $n=5$ to the ground state ($n=1$) is given by $n(n-1)/2 = 5(4)/2 = 10$.
