The figure below represents part of the emission spectrum for aone-electron ion in the gas phase. All the lines result fromelectronic transmissions from excited states to the n = 3state.

✔ 最佳答案

In this series (Paschen series), all lines are resulted from electronictransition from an excited state to n = 3 state
The 1st line: from n = 4 to n = 3
The 2nd line: from n = 5 to n = 3
The 3rd line: from n = 6 to n = 3
etc.

A is the 3rd line,
and it corresponds to electronic transition from n = 6 to n = 3.

B is the 2nd line,
and it corresponds to electronic transition from n = 5 to n = 3.
