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.
A metallic bond
The strength of metallic bonding arises from the delocalized sea of electrons that are free to move throughout the metal lattice, creating strong electrostatic attractions between positively charged metal ions and the negatively charged electron cloud. This electron mobility contributes to properties such as electrical conductivity and malleability, allowing metals to deform without breaking. Additionally, metallic bonds are typically non-directional, which enhances the structural integrity of metals under stress. Overall, these features make metallic structures robust and versatile for various applications.
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.
Cells are the basic structural units of tissues and can change in size depending on various factors. To confirm that the units in question are cells, you can perform a microscopic examination to observe their typical cellular structures such as a cell membrane, cytoplasm, and nucleus. Additionally, cells are often surrounded by an extracellular matrix that provides support and structure to the tissue.

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.
Do you mean "nucleotide"? Nucleotides are molecules that, when joined together, make up the structural units of RNA and DNA.
Atoms are the structural units of elements that make up matter. Each element is made up of one type of atom, which consists of a nucleus containing protons and neutrons, surrounded by electrons. Different elements have different numbers of protons in their nuclei, giving them distinct chemical properties.
