structure

Examples of structure in the following topics:

• Ownership Structures

• Structural Classification of Joints

• Overall Structure and Formatting of an APA Paper

• Structure of a Sentence

• Overall Structure and Formatting of an MLA Paper

• Structure of the Directory

• Resonance

  • However, for some molecules not all the bonding possibilities cannot be represented by a single Lewis structure; these molecules have several contributing or "resonance" structures.
  • Each contributing resonance structure can be visualized by drawing a Lewis structure; however, it is important to note that each of these structures cannot actually be observed in nature.
  • The structure contains two N-O single bonds and one N=O double bond.
  • Therefore, three valid resonance structures can be drawn.
  • Because atoms with electric charges are not as stable as atoms without electric charges, these resonance structures will contribute less to the overall resonance structure than a structure with no charges.

• Vestigial Structures

  • These unused structures without function are called vestigial structures.
  • Vestigial structures are often homologous to structures that function normally in other species.
  • In some cases the structure becomes detrimental to the organism.
  • The vestigial versions of a structure can be compared to the original version of the structure in other species in order to determine the homology of the structure.
  • Homologous structures indicate common ancestry with those organisms that have a functional version of the structure.

• Overview of Organizational Structure

  • Business organizations can be structured in various ways, depending on their standing as legal entities, internal structure, and management processes .
  • Also called a "product structure," the divisional structure groups each organizational function into a division.
  • This structure can combine the best of both separate structures.
  • All of these structures are for profit, but there are also non-profit corporations and other structures.
  • Some common structures are the functional, divisional, matrix, team, network, and modular structures.

• Lewis Structures for Polyatomic Ions

  • The Lewis structure of an ion is placed in brackets and its charge is written as a superscript outside of the brackets, on the upper right.
  • Non-valence electrons are not represented in Lewis structures.
  • After the total number of available electrons has been determined, electrons must be placed into the structure.
  • Lewis structures for polyatomic ions are drawn by the same methods that we have already learned.
  • When the Lewis structure of an ion is written, the entire structure is placed in brackets, and the charge is written as a superscript on the upper right, outside of the brackets.
