Chemistry · Classification of Elements and Periodicity in Properties

हिन्दी

Identify the transition metal that has the outermost electronic configuration \( (n-1)d^{10}ns^2 \) and does not show most of the typical properties of transition elements like catalytic activity or colored ion formation.

  1. Scandium (\( \text{Sc} \))
  2. Copper (\( \text{Cu} \))
  3. Iron (\( \text{Fe} \))
  4. Zinc (\( \text{Zn} \))

Correct answer · Option 4

Zinc (\( \text{Zn} \))

Explanation

Elements like Zn, Cd, and Hg have completely filled \( (n-1)d^{10}ns^2 \) configurations in their ground state as well as common oxidation states, and thus do not show typical transition metal properties.
