With increase in number of unpaired electrons, paramagnetism:

Correct answer: A. Increases.

  • A. Increases.
  • B. Decreases.
  • C. Remains constant.
  • D. Decreases then increases.

Explanation

Paramagnetism is due to the presence of unpaired electrons in the material, so most atoms with incompletely filled atomic orbitals are paramagnetic, although exceptions such as copper exist. Due to their spin, unpaired electrons have a magnetic dipole moment and act like tiny magnets.

About Electronic Configuration

Electronic configuration describes how electrons occupy shells, subshells and orbitals around an atom. Questions use the Aufbau principle, Pauli exclusion principle and Hund's rule to write configurations, identify valence electrons, form ions and explain periodic trends, including common exceptions such as chromium and copper.
