NEET Chemistry: Class 11, Chapter 3: Classification of Elements and Periodicity in Properties questions with solutions

Q1. Compare the properties of a typical metal and a non-metal on the basis of the following. Conductivity of heat and electricity:

1. Metals are good conductor of heat and electricity
2. Non metals are good conductor of heat and electricity
3. Metals are bad conductor of heat and electricity
4. Both B and C

Answer: Metals are good conductor of heat and electricity

Metals have delocalized electrons that move easily through the structure, so they conduct heat and electricity well. Non-metals generally lack these free-moving charge carriers, so they are usually poor conductors.
