Text Solution

AI Generated Solution

To determine which element has only one electron in the d-orbitals, we can follow these steps: ### Step 1: Identify the Transition Metals Transition metals are elements that have partially filled d-orbitals. These elements are found in the d-block of the periodic table. ### Step 2: Determine the Atomic Number of Scandium The first transition metal is Scandium (Sc), which has an atomic number of 21. ...
