Question

Give reason. 1. Metals are good conductors of electricity. ​

Answer 1

Explanation:

Metals are an excellent conductor of electricity and heat because the atoms in the metals form a matrix through which outer electrons can move freely. Instead of orbiting their respective atoms, they form a sea of electrons that surround the positive nuclei of the interacting metal ions. The electrons then move freely throughout the electron sea. Glass is used as an insulator because it has atoms that have electrons that are closely connected with each other. Silver is the strongest conductor out of all known materials. However, because silver is a relatively costly and sought-after material, it is not frequently used for its conductive properties. Copper is less conductive than silver but is cheaper and commonly used as an effective conductor in household appliances.
