Question

is the particle below paramagnetic or diamagnetic? $ce{zn^{2+}}$
paramagnetic diamagnetic

Explanation:

Paramagnetic substances have unpaired electrons, while diamagnetic substances have all electrons paired. Zinc (Zn) has an atomic number of 30, so its neutral electron configuration is $[Ar] 3d^{10} 4s^2$. When it forms $Zn^{2+}$, it loses 2 electrons from the 4s orbital, resulting in the electron configuration $[Ar] 3d^{10}$. All electrons in this configuration are paired.

Answer:

diamagnetic
