Question

Which of the following is characteristics of d block elements?

• A. They show variable oxidatation states
• B. Atomic radius do not change regularly as we move from left to right across the first transition series
• C. They have tendency to form coordination compounds
• D. all of the above

Answer 1

The correct option is D all of the above

A) Since the difference in energy of orbitals is less. Hence it shows variable oxidation state.
B) Due to shielding effect, atomic radius do not change regularly as we move from left to right across the first transition series.
C) They have greater tendency to form coordination compounds ecause of their small size, high charge and availability of low energy orbitals.
