Which of the following transition metal ions will have definite value of magnetic moment:
Correct answer: B. Tc+
- A. Sc3+
- B. Tc+
- C. Cu+
- D. Zn2+
Explanation
Technetium in its +1 oxidation state would have a definite value of magnetic moment due to its unpaired electron(s), while all other options have completely filled d orbitals and thus have magnetic moments of 0.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
