Glass is known to be a good insulator because atoms in glass hold on tightly to their positively charged particles.
Insulators are those substances that do not conduct heat or electricity like their conductor counterparts.
Conduction of electric charges is as a result of the free flow of electrons in the atom of the substance.
Hence, a good insulator holds on tightly to its electrons and prevent them from flowing freely to conduct electric charges.
Therefore, Glass is known to be a good insulator because atoms in glass hold on tightly to their positively charged particles.
