Paramagnetic behavior of an atom, ion or molecule is due to presence
Correct answer: A. Unpaired electrons
- A. Unpaired electrons
- B. Paired electrons
- C. Protons
- D. Neutrons
Explanation
A is correct as the presence of unpaired electrons results in a weak attraction to magnets.An unpaired electron has a magnetic dipole moment, while an electron pair has no dipole moment because the two electrons have opposite spins so their magnetic dipole fields are in opposite directions and cancel. Thus an atom with unpaired electrons acts as a magnetic dipole and interacts with a magnetic field.B is incorrect as the presence of paired electrons results in diamagnetism.C is incorrect as magnetism isnt affected by protons.D is incorrect as magnetism isnt affected by neutrons

About Electronic Structure of d-Block Elements
The electronic structure of d-block elements covers the filling of the (n-1)d and ns orbitals, general electronic configurations, and the exceptions shown by chromium and copper. It explains how partially filled d orbitals produce variable oxidation states, coloured ions, magnetic behaviour and complex formation, while distinguishing transition elements from elements with completely filled d subshells.
