Why is glass a good insulator? The atoms in glass hold on tightly to their positively charged particles. The atoms in glass do not hold on tightly to their negatively charged particles. The atoms in glass do not hold on tightly to their positively charged particles.

Answer 1

The first statement is correct. Glass is a good insulator because the atoms in glass hold on tightly to their positively charged particles (protons) and do not allow them to move freely. This prevents heat from easily transferring through the material because heat is essentially the movement of the charged particles. Additionally, the structure of glass is such that it does not have a lot of free electrons that can carry heat energy easily, further contributing to its insulating properties.
