Paramagnetic behavior of an atom, ion or molecule is due to the presence of:
Correct answer: B. Unpaired electrons
- A. Paired electrons
- B. Unpaired electrons
- C. Protons
- D. Neutrons
Explanation
The paramagnetic behavior of an atom, ion, or molecule is due to the presence of unpaired electrons. In paramagnetic substances, the individual atoms, ions, or molecules possess one or more unpaired electrons in their electron configurations. These unpaired electrons have a magnetic moment associated with their spin, and they can align their spins with an external magnetic field. As a result, paramagnetic substances are weakly attracted to an external magnetic field.

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.
