Conductors and Insulators with Examples – Class 6 Science

What are conductors? Conductors are substances that allow electricity to pass through them freely.  This is because these substances contain many atoms in which the outermost electrons (valence electrons) are loosely bound.  Metals are good conductors of electricity due to the presence of a valence electron or valence electrons which are loosely bound.  In an electric circuit, these electrons can freely move around the circuit with a domino-like effect.  Metals are found towards the right of the periodic table.  Can you name a metal which you are familiar with which is used in electrical wiring?  Copper is used for electrical wiring because each copper atom has only one valence electron which can be easily freed.  Thus, it can easily be harnessed in electricity as it is an excellent conductor. Can you think of a few substances which are conductors of … Continue reading
