What type of structure does a metallic lattice typically have?

A metallic lattice typically exhibits a structure characterized by a high boiling point and the ability to conduct heat and electricity effectively. This arises from the unique arrangement of metal atoms, which are packed closely together in a regular pattern, forming a lattice structure.

In this arrangement, the outer electrons of the metal atoms are not bound to any specific atom but instead are delocalized, creating what is often referred to as a "sea of electrons." This free movement of electrons is what allows metals to conduct electricity, as these electrons can move under an electrical potential. Likewise, the ability of these delocalized electrons to transfer energy facilitates the conduction of heat through the metallic structure.

The high boiling point is largely a result of the strong metallic bonds present throughout the lattice. These bonds require significant energy to break during phase changes, such as from solid to liquid. Therefore, the properties of high boiling point and good conductivity are inherently linked to the metallic lattice structure, which reinforces why this option is the correct characterization of such materials.
