Question

Which from following statements is NOT correct?

• A. All alkali metals are silvery white.
• B. Density of potassium is less than sodium.
• C. Compounds of group-1 elements are diamagnetic.
• D. Melting point of group-1 elements increase down the group.

Hint:

Logic Tip: Unlike halogens whose melting/boiling points increase down the group due to increasing van der Waals forces, metals typically see a decrease in melting points down a group because larger atomic radii result in weaker metallic bonds.

Answer 1

The Correct Option is D
