Question

which of the following is paramagnetic 1. Cu2+ 2. Ag+ 3.Zn2+ 4.Au+​

Answer 1

Answer:

1. CU²⁺

Explanation:

Paramagnetism is a form of magnetism whereby some materials are weakly attracted by an externally applied magnetic field, and form internal, induced magnetic fields in the direction of the applied magnetic field.

∵CU²⁺  electronic configuration is 3d10 and does not any unpaired electron but in CU²⁺ electronic configuration of copper is 3d9 with 1 unpaired electron so it will be paramagnetic.
