Apparatus used to measure the deflection of gaseous \(\text{Fe}^{2+}\) ions in an inhomogeneous magnetic field.
Apparatus used to measure the deflection of gaseous \(\text{Fe}^{2+}\) ions in an inhomogeneous magnetic field.
A beam of isolated gaseous iron(II) ions, \(\text{Fe}^{2+}\text{(g)}\), produced from neutral iron atoms (\(\text{Fe}\), atomic number \(26\)), is passed through an inhomogeneous magnetic field using the apparatus shown below to determine its magnetic behavior.

Which of the following correctly identifies the ground-state electron configuration of \(\text{Fe}^{2+}\text{(g)}\) and predicts its behavior in the magnetic field?
