Electrons move freely in a solid, as in a metal
Electrons move freely among many metal nuclei
In electrical insulators electrons are not able to move freely.
trueThe free-moving electrons in metals account does hold many of the properties of metals. There are three properties.
electrons move freely among many metal nuclei
Metals are materials in which particles (electrons) can freely move. If you mean bigger particles (such as atoms or molecules), then liquids and gasses allow easy movement
Conductors are substances where electrons can freely move from atom to atom.
metal conducts electricity because it allows electrons to move freely as well as it has free electrons, unlike insulators(non-metals) which do not have free electrons. When the electrons are allowed to move freely in a substance, it is a good conductor and allows electric charge to flow.
insulator...as opposed to a conductor which does allow electrons to travel freely within it.
The material is conductive. Metals (copper or aluminum, etc) allows charged particles of electrons to move freely in either direction along their length.
protons????

insulator
A materiel that allows an electric charge to pass through it is an conducter (copper, for example)
Yes, electrons move freely in metals.
The characteristic that allows some metals to be better conductors of electricity is that they have 'free electrons'. Free Electrons simply means that there is a weaker bond between the electrons on the outer valence shell to the nucleus of the atom, than other atoms. This weak bond allows electrons in metals to become more easily excited (when mechanical means of generation occurs), where the electrons are able to transfer from one atom to another. I imagine this is what the question is asking. Basically, electricity is inherent in the material. Metals have weak bonds in their outer valence electron shell. A: In metals, the atoms move freely, allowing heat to travel faster. :)
The purpose of a wire is to carry some sort of electrical signal. This requires that the electrons in the material be able to move freely. Materials with free movable electrons are called "metals".
In electrical insulators electrons are not able to move freely.
