Write the condensed electron configuration of each transition metal ion, and predict whether it is paramagnetic:
(a) V³⁺ (Z = 23)
(b) Ni²⁺ (Z = 28)
(c) La³⁺ (Z = 57)

Respuesta :

Answer:

a. V³⁺ (Z = 23) => [Ar] 3d2 : Paramagnetic

b. Ni²⁺ (Z = 28) => [Ar] 3d8 :

Paramagnetic

c. La³⁺ (Z = 57) => [Xe] : not paramagnetic

Explanation: Paramagnetic is attribute to the presence of unpaired elections in the electronic configuration.
