Unformatted text preview: difference in ionization energies generally means that electrons will be "pinned" at the atoms with the higher ionization energies, resulting in the creation of ions. An element such as carbon would not be expected to form a metallic solid because it does not have a low enough ionization energy; instead, it tends to form molecular solids or extended solids with covalent bonding. 2.
