Source sentences:
text: For caesium it is so strong that the electrons are virtually free from the caesium atoms to form a gas constrained only by the surface of the metal.
text: Conductive nonmetals (such as graphite), molten ionic compounds, and aqueous ionic compounds conduct electricity for the same reason—electrons are free to move around.
text: This model may account for: Conductivity: Since the electrons are free, if electrons from an outside source were pushed into a metal wire at one end (Figure \(\PageIndex{2}\)), the electrons would move through the wire and come out at the other end at the same rate (conductivity is the movement of charge).
text: Metals are good conductors because they have free electrons.
text: : Metals are good conductors because they have free electrons.
text: There also are few non-metals which conduct electricity: graphite (because, like metals, it has free electrons), and ionic compounds that are molten or dissolved in water, which have free moving ions.
text: In other words, metals have free electrons.
text: Further, because the electrons are free to move away from each other, working a metal doesn't force together like-charged ions, which could fracture a crystal through the strong repulsion.
text: The electrons are free to move throughout the resulting network.
text: Since these electrons are free to move within the crystal structure, metals are good conductors of electricity and heat.
