Iconic solids are primarily composed of ions arranged in a regular, repeating three-dimensional lattice structure. These solids are formed when cations and anions attract each other due to electrostatic forces, resulting in a stable configuration. The arrangement of these ions maximizes attraction while minimizing repulsion, leading to characteristic properties such as high melting points and electrical conductivity when dissolved in water or molten. Examples of iconic solids include sodium chloride (NaCl) and magnesium oxide (MgO).
Network solids are composed of an extended three-dimensional network of atoms bonded together by covalent bonds. Examples include diamond and quartz. The structural units in network solids are individual atoms or small groups of atoms connected to each other in a repeating pattern throughout the solid.
Nonmetal atom
Metallic solids are primarily composed of closely packed metal atoms that are held together by metallic bonds. In these solids, the atoms are arranged in a regular lattice structure, allowing for the delocalization of electrons, which contributes to their conductivity and malleability. The arrangement can vary, with common structures including face-centered cubic (FCC), body-centered cubic (BCC), and hexagonal close-packed (HCP). The presence of free-moving valence electrons is a key characteristic that distinguishes metallic solids from other types of crystalline solids.

The fiber-like protein units that make up the cell's cytoskeleton, mitotic spindle, and centrioles in animal cells are called microtubules. These tubular structures play crucial roles in cell division, cellular organization, and structural support.

In network solids, the basic structural units are atoms or ions held together by covalent bonds to form a three-dimensional network structure. These units are interconnected through strong chemical bonds in all directions, creating a continuous lattice structure. Examples of network solids include diamond (carbon atoms) and quartz (silicon and oxygen atoms).

Amino acids are the basic structural building units of proteins.
Nucleotides are molecules that, when joined together, make up the structural units of RNA and DNA.
