If the last electron (i.e. the differentiating electron) occupies 5f -

1.	If the last electron (i.e. the differentiating electron) occupies 5f - orbital, the element is said to belong 5f - series. In this series, ions having 5f0, 5f1 and 5f14 are colourless. The colour of U3+ is red which is due to(a) d - d transition(b) f - f transition(c) crystal defect(d) L \(\rightarrow\) M charge transfer
Answer» Answer is : (b) f - f transition Colour of U³⁺ is due to transition of electron from lower electronic energy level of f-orbital to higher electronic energy level of f - orbital. This type of transition is known as f - f transition.
