Answer 2

Both assertion and reason are false.

Explanation:

• Sodium is an element and its atomic number is 11.
• The symbol for sodium is Na.
• The colour of sodium is silvery-white and it is soft and highly reactive metal.
• One of the good conductor of electricity is sodium and it is not a bad conductor of electricity.
• In the presence of air, sodium oxidizes rapidly and hot hydrogen gas is released in water. Hence, it cannot be used in electrical wires.
• Copper is used in electrical wires because it carries more current due its metallic properties and it is a good conductor of electricity.
• Since, the sodium metal is soft, it can be cut with a knife.
