Question

Metallic elements are described by their standard electrode potential, fusion enthalpy, atomic size, etc. The alkali metals are characterised by which of the following properties?

• A. High negative standard electrode potential
• B.
  High boiling point
• C. Large atomic size
• D. High density

Answer 1

Answer: (A), (C)

Large atomic size

Solution:
Out of the given properties, alkali metals are characterised by their high negative standard electrode potential and large atomic size.

Alkali metals are characterised by being soft and light. They have low boiling points and also low density due to their large atomic size.

Hence, (B) and (D) are correct.
