Why is glass a good insulator?
The atoms in glass hold on tightly to their negatively charged particles.
The atoms in glass do not hold on tightly to their negatively charged particles.
The atoms in glass hold on tightly to their positively charged particles.
The atoms in glass do not hold on tightly to their positively charged particles.
The correct answer is: The atoms in glass do not hold on tightly to their negatively charged particles.
The correct answer is "The atoms in glass do not hold on tightly to their electrons."
This means that glass has a low conductivity, which makes it a good insulator. When an electric field is applied to glass, the electrons cannot move freely, and thus the energy cannot flow through the material. This property makes glass an excellent choice for insulating windows and other applications that require thermal or electrical insulation.
