Question

Which of the following statement is correct?

• A. Down the group strength of metallic bonds increases nearly in all transition elements
• B. Down the group strength of metallic bonds increases in alkali metals
• C. Down the group strength of metallic bonds decreases in transition metals
• D. None of the above

Answer 1

The correct option is A Down the group strength of metallic bonds increases nearly in all transition elements

As we move down the group strength of metallic bonds increases nearly in all transition elements because as we move down from 3d to 5d there is more frequent metal-metal bonding due to better overlap of orbitals.
As the atomic size increases on moving down the group in alkali metals, the strength of the metallic bonds decreases due to increase in the atomic size.
