WebDescribe metallic crystals. Key Points Atoms in metals lose electrons to form cations. Delocalized electrons surround the ions. Metallic bonds (electrostatic interactions between the ions and the electron cloud) hold the metallic solid together. Atoms are arranged like closely packed spheres. Webmetallic bondA chemical bond in which mobile electrons are shared over many nuclei; this leads to electrical conduction. Metallic Bonding Metallic bonding may be described as the sharing of free electrons among a lattice of positively charged metal ions.
