Cu+2 salts are:
Correct answer: A. Paramagnetic
- A. Paramagnetic
- B. Diamagnetic
- C. Ferromagnetic
- D. None of these
Explanation
Cu+2 salts are paramagnetic. Paramagnetism is a property exhibited by certain substances that are attracted to an external magnetic field. It occurs when unpaired electrons are present in the atoms or ions of the substance. These unpaired electrons align their spins with the applied magnetic field, leading to a net magnetic moment and attraction to the field. In the case of Cu2+ ions, they have an electron configuration of [Ar]3d9. In this configuration, there are two unpaired electrons, which make Cu2+ ions paramagnetic. These unpaired electrons align with an external magnetic field, causing the Cu2+ salts to be attracted to the 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.
