Question: is zn+2 paramagnetic or diamagnetic?
Answer: Answer: Hii dear!!! In +2 state of Zn, Zn(30) becomes Zn(28) i.e. electronic configuration is [Ar]3d104s0 , so here 2 electron is out from 4s-orbital , which results in no unpairing of electron i.e. in +2 state also Zn has all electrons paired, so it is diamagnetic .
