Final answer:
Ionic compounds have a different molecular structure compared to substances like glass or polythene, resulting in no electron attraction forces in the latter due to covalent bonding and nonpolar characteristics.
Explanation:
Contrary to the nature of ionic bonds, substances like glass or polythene do not exert attraction on their electrons due to their molecular structure. Glass and polythene are composed of covalent bonds where electrons are shared rather than transferred, leading to no net charge imbalance to generate attraction.
For example, in glass, the atoms are arranged in a random structure without a consistent repeating pattern, preventing electron attraction forces to be established like in ionic compounds.
Moreover, polythene has long carbon chains with hydrogen atoms attached, creating a nonpolar molecule that lacks significant positive or negative charges to exert electron attraction forces.
