Atoms of materials that are good conductors of electricity have
A) mostly protons; thus, the negative charges jump easily from atom to atom.
B) only electrons, and so these electrons are easily moved.
C) outer electrons which are loosely bound and thus easily moved.
D) no electrons; thus, any that are given to them are easy to move about.

Question

Quizplus · Accepted Answer

Materials that are good conductors of electricity have outer electrons that are loosely bound and able to move easily. This allows for the easy flow of electrons between atoms and hence make them good conductors of electricity. Choice A and D are incorrect because the presence of protons and electrons is necessary for the atom to exist and be able to conduct electricity. Choice B is incorrect because it implies that only electrons are present in conductive materials, which is not the case.
