Question

predict the magnetic nature of divalent ions in aqueous solution if its atomic number is 30,29,26

Answer 1

Answer:

Explanation:

atomic number 30 zinc

divalent ion Zn²⁺ electronic configuration = 3d¹⁰ all electrons are paired hence diamagnetic

atomic number 29 copper  4S¹ 3d¹⁰

divalent cation electron configuration 3d⁹ one unpaired electron hence paramagnetic

atomic number 26 iron

divalent electronic configuration = 3d⁶    4 unpaired electrons hence paramagnetic
