Furthermore, sodium is an excellent conductor of both heat and electricity, a property explained by the mobility of the free electrons throughout the lattice. A sodium atom has 11 electrons, arranged in the configuration 1s² 2s² 2p⁶ 3s¹.
Understanding Sodium Solid State Bonding Mechanism
This structure is often visualized as a lattice of positive ions bathed in a sea of negative charge. Luster: The free electrons absorb and re-emit light, giving sodium its shiny, reflective appearance.
The space between these cores is filled with a uniform, mobile electron gas. Electrical Conductivity: The delocalized electrons act as charge carriers, moving freely when a voltage is applied.
Understanding Metallic Bonding in Sodium's Solid State Structure
Covalent bonding, which involves the sharing of electron pairs between specific atoms, is also absent in pure sodium. Thermal Conductivity: Electrons transfer kinetic energy rapidly through the structure, distributing heat efficiently.
