Question

Electrons moving like molecules of a gas exist in:

Answer 1

Metals:-

• Metals have electrons that are free to move and are delocalized as gas molecules.
• Metallic bonding do not entail electron sharing.
• The s and p valence electrons of metals are maintained loosely. They depart with their "own" metal atoms.
• This creates an "electronic sea" that surrounds the metal cations in the solid. Electrons are able to travel freely in this electron sea.
• The valence electrons in this model are free, delocalized, and mobile. Electrons migrate between all atoms.
• Because electrons are delocalized, electric charge may be transmitted across a metal; hence, metals are electrically conductive.
• Heat can also be transmitted through electron mobility (metals are also heat conductive).

Thus, electrons moving like molecules of gas exist in - metal.
