Is neon (Ne) paramagnetic or diamagnetic?
Answer: neon ( Ne ) is a Diamagnetic. What is Paramagnetic and Diamagnetic ? Paramagnetic. Paramagnetism is a form of magnetism whereby certain materials are weakly attracted by an externally applied magnetic field, and form internal, induced magnetic fields in the direction of the applied magnetic field.
