D. How were noblegases discovered?
E. How were noblegases understood in the past?
F. what are theapplications of noble gases?
5because of their properties, noble gases have many importantapplications. They are widely used in medicine and industries. For instance,liquid Helium is used for superconducting magnets(磁體).These magnets are very important in physics and medicine. When a doctorsuspects that a person’s brain has been damaged, he might request for MagneticResonance Imaging(MRI). MRI allows the doctor to “see” the brain, withoutoperating on the patient.
