NEET The d and f Block Elements — Set 6

Question 1

Which of the following transition metal compounds is diamagnetic?

Accepted Answer

ZnSO 4 contains Zn 2+ with 3d 10 configuration (all electrons paired).

Question 2

Which of the following is NOT a use of transition metals or their compounds?

Accepted Answer

Transition metals and their compounds are used as catalysts, pigments, and in alloy formation. While platinum is used as an inert electrode in many electrochemical setups, the option 'inert electrodes' may be considered not primary/general for most transition metals.

Question 3

Which of the following statements about interstitial compounds is correct?

Accepted Answer

Interstitial compounds are formed when small atoms occupy voids in metal crystal lattices.
