GEOLOGY

Detailed explanation-1: -These types of materials allow electrons to flow freely and fluidly from one point to another if they are connected to a power source. Metals like copper, iron, gold, aluminum, and silver are the best materials for conducting electricity.

Detailed explanation-2: -Materials with high electron mobility (many free electrons) are called conductors, while materials with low electron mobility (few or no free electrons) are called insulators.

Detailed explanation-3: -Metals have loosely bound outer electrons that is they have charge carriers which can move easily (current) when a potential difference is applied. Therefore, these loosely bound outer electrons make metals good conductors.

Detailed explanation-4: -In a conductor, the outer elec-trons of the atoms are loosely bound and free to move through the material. In fact, the electrons are so mobile, that they are sometimes described as an electron gas, in which the atomic nuclei rest.

Detailed explanation-5: -In a conductor, electrical charge carriers, usually electrons or ions, move easily from atom to atom when voltage is applied. Most metals like copper are considered good conductors, while nonmetals are considered bad conductors–that is, insulators.
