Question

Which of the two is good conductor of heat and electricity: sodium or chlorine.

Answer 1

1. Good conductors: Materials that allow heat and electricity to pass through them easily are called good conductors.
2. Sodium is a good conductor of heat and electricity because it is metal and metals are a good conductor.
3. The reason metals conduct heat and electricity so well is that the electrons in them can move around easily, and they can carry heat from one part to another.
4. Metal atoms are packed more densely and can transmit heat vibrations more readily.
5. While most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them.

Hence, sodium is a good conductor of heat and electricity.
