Covalent bonding, which involves the sharing of electron pairs between specific atoms, is also absent in pure sodium. Electrical Conductivity: The delocalized electrons act as charge carriers, moving freely when a voltage is applied.
Understanding How Metallic Bonding Holds Sodium Together
The single electron in the outermost 3s orbital is only weakly held by the nucleus due to shielding by the inner electron layers. Sodium's Electron Configuration To understand why sodium specifically exhibits metallic bonding, one must look at its atomic structure.
This "sea of electrons" acts as a powerful adhesive, providing strong electrostatic attraction between the mobile negative charges and the fixed positive ions. The Nature of Metallic Bonding Metallic bonding is the primary type of bonding that holds elemental sodium together in its solid state.
Why Metallic Bonding Holds Sodium Together
Understanding how this reactive element maintains its solid structure requires a deep dive into the forces that bind its atoms. This structure is often visualized as a lattice of positive ions bathed in a sea of negative charge.
