Transition elements are the elements that are found in Groups 3-12 of the modern periodic table, that constitute the _____.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. d-block.
Transition elements are the elements found in Groups 3-12 of the modern periodic table, and they constitute the d-block. These elements are characterized by having partially filled d-orbitals in their common oxidation states. Transition elements exhibit unique properties such as variable oxidation states, the ability to form colored compounds, and the presence of magnetic behavior due to unpaired d-electrons. They play important roles in various biological, industrial, and catalytic processes.
