How many of the following are paramagnetic in nature : $Fe^{+ 2}, Mn^{+ 3}, Cr^{+ 3}, Zn^{+ 2}, Na^{+}, Ca^{+ 2}$

Answer:

Solution:

Species: Fe²⁺ (d⁶ → 4 unpaired), Mn³⁺ (d⁴ → 4 unpaired), Cr³⁺ (d³ → 3 unpaired), Zn²⁺ (d¹⁰ → 0), Na⁺ (0), Ca²⁺ (0)

Paramagnetic = species with unpaired electrons

Answer: 3 (Fe²⁺, Mn³⁺, Cr³⁺)
