Scandium forms no coloured ions, yet it is regarded as a transition elements. Explain why?

Text Solution

AI Generated Solution

To explain why scandium forms no colored ions yet is regarded as a transition element, we can break down the explanation into several steps: ### Step-by-Step Solution: 1. **Identify Scandium as a Transition Element**: - Scandium (Sc) has an atomic number of 21 and is located in the d-block of the periodic table. Transition elements are defined as elements that have an incomplete d-subshell in one or more of their oxidation states. 2. **Electronic Configuration of Scandium**: ...
