Question

Explain the following with reasons:
Sodium is softer than copper, but both are very good electrical conductors.
​

Answer 1

Answer:

$\huge\red{\underline{\overline{\mathbb{ληsωεя:-}}}}$

In case of copper the number of delocalized electron is larger than the sodium and also the metallic radius of sodium is more than that of copper so sodium is softer than the copper. But both are good conductor of Electricity due to availability of free electrons.
