Detailed explanation-1: -Metals are elements that are good conductors of electric current and heat. They also tend to be shiny and bendable – like copper wire. The majority of elements in the periodic table are metals.
Detailed explanation-2: -Plastic, rubber, wood, and ceramics are good insulators. These are often used to make kitchen utensils, such as saucepan handles, to stop heat from flowing up to burn the cook’s hand. Plastic coating is also used to cover most electrical wires in appliances. Air is also a good insulator of heat.
Detailed explanation-3: -Iron Conductivity Iron has metallic bonds which is where the electrons are free to move around more than one atom. This is called delocalization. Because of this, iron is a good conductor.
Detailed explanation-4: -Plastics do not conduct electricity and are, therefore, bad conductors of electricity.
