The World of Metals and Non-metals — Science STD 7 — Question

Metals and non-metals differ significantly in their ability to conduct electricity and heat, which is a key factor in their classification. Metals are generally excellent conductors of both electricity and heat, while non-metals are typically poor conductors.
Metals: Metals have a unique atomic structure that allows electrons to move freely. These free electrons can easily carry electrical charge or thermal energy through the material. Metals like copper, aluminum, and iron are widely used in electrical wiring and cooking utensils because of their high conductivity.
Non-metals: Non-metals lack the free electrons that metals possess. As a result, they do not conduct electricity or heat efficiently. Materials like wood, plastic, and rubber are used as insulators in electrical applications and as handles for cookware to prevent the flow of electricity or heat.
