But solid calcium has a metallic structure. Q. Identify whether the ions are diamagnetic or paramagnetic… O. The process of deriving the MO diagram for a metallic solid is obviously more complicated than this, but the answer to your question is that a single Cu 0 atom is paramagnetic, but Cu 2 would be diamagnetic. It's Cu+1, paramagnetic. In Cu(I) compound has completely filled d orbital which means no unpaired electrons, therefore it is diamagnetic and due to this, it does not show any transition hence white in colour. The Quora Platform does not have a direct text formatting features. When a material is placed within a magnetic field, the magnetic forces of the material's electrons will be affected. Diamagnetic, Paramagnetic, and Ferromagnetic Materials. The electronic configuration of Cu(II) : [Ar] 3d 9 4s 0 The six d electrons would therefore be in the lower set, and all paired. Diamagnetic materials are repelled by a magnetic field; an applied magnetic field creates an induced magnetic field in them in the opposite direction, causing a repulsive force. Iron(III) Paramagnetic (1 lone electron). The key difference between paramagnetic and diamagnetic materials is that the paramagnetic materials get attracted to external magnetic fields whereas the diamagnetic materials repel from the magnetic fields.. Materials tend to show weak magnetic properties in the presence of an external magnetic field.Some materials get attracted to the external magnetic field, whereas some … Paramagnetic. C. square planar and paramagnetic. 0 of 3 completed. Chemistry Questions & Answers for CAT,Bank Exams,AIEEE, Bank PO,Bank Clerk,Analyst : Is C2 Paramagnetic or Diamagnetic? Knowing this complex has magnetic properties. Since there are any unpaired electrons in the atom, it is considered paramagnetic.
