Final answer:
In pure metals, particles are arranged in a closely packed structure called a crystal lattice. The lattice consists of positive metal ions surrounded by a sea of delocalized electrons held together by metallic bonds.
Step-by-step explanation:
Arrangement of particles in pure metals
In pure metals, the particles are arranged in a closely packed structure known as a crystal lattice. The lattice consists of positive metal ions surrounded by a sea of delocalized electrons. The metal ions are held together by metallic bonds, which are formed due to the electrostatic attraction between the positive ions and the negatively charged electrons.
Within the lattice, the metal ions are arranged in a repeating pattern. This arrangement allows for the high electrical and thermal conductivity observed in metals, as well as their malleability and ductility.
