Is nickel paramagnetic?
The magnetism of elements depends upon the presence of paired and unpaired electrons in their last orbitals. Let us see whether nickel metal is paramagnetic or not.
Nickel metal is paramagnetic due to its incomplete subshell. It has unpaired electrons. Thus, applying an external magnetic field attracts the magnetic towards itself and shows a paramagnetic nature.
