Ionic Compounds: Formulas and Nomenclature

88.1K
An element composed of atoms that readily lose electrons (a metal) can react with an element composed of atoms that readily gain electrons (a nonmetal) to produce ions through complete electron transfer. The compound formed by this transfer is stabilized by the electrostatic attractions (ionic bonds) between the oppositely charged ions.

Molecular Compounds: Formulas and Nomenclature

Molecular compounds or covalent compounds result when atoms share electrons to form covalent bonds. Since there is no electron transfer, molecular compounds do not contain ions; instead, they consist of discrete, neutral molecules.

Coordination Compounds and Nomenclature

In most main group element compounds, the valence electrons of the isolated atoms combine to form chemical bonds that satisfy the octet rule. For instance, the four valence electrons of carbon overlap with electrons from four hydrogen atoms to form CH4. The one valence electron leaves sodium and adds to the seven valence electrons of chlorine to form the ionic formula unit NaCl (Figure 1a). Transition metals do not normally bond in this fashion. They primarily form coordinate covalent bonds, a...

Language01:16

Language

921
Language is a unique communication system that uses words and systematic rules to organize and transmit information. Unlike other forms of communication, which may involve postures, movements, odors, or vocalizations, language relies on symbols and grammar. This makes human communication distinct from that of other species, who also communicate but do not use language in the same way humans do.
Corballis and Suddendorf (2007) and Tomasello and Rakoczy (2003) highlight the role of language in...

Common Ion Effect03:24

Common Ion Effect

47.0K
Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Châtelier’s principle. Consider the dissolution of silver iodide:

Components of Language01:24

Components of Language

830
Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs.

Area of Science:

  • Allergy and Immunology
  • Bioinformatics
  • Molecular Biology

Background:

  • A systematic nomenclature for allergens was established in the early 1980s to standardize naming conventions.
  • The World Health Organization/International Union of Immunological Societies (WHO/IUIS) Allergen Nomenclature Sub-Committee was formed in 1986 to manage this standardization.
  • The initial aim was to standardize names for antigens causing IgE-mediated allergies in humans.

Purpose of the Study:

  • To standardize the nomenclature for allergens causing IgE-mediated allergies.
  • To maintain and revise the Allergen Nomenclature database, currently hosting approximately 880 proteins.
  • To address challenges posed by new 'omics' technologies in identifying potential allergens.

Main Methods:

  • Development of a nomenclature based on Linnaean taxonomy.
  • Establishment of evidence-based criteria for reviewing allergen candidates.
  • Assessment of biochemical analysis and proof of allergenicity for submitted candidates.
  • Review of confidential data demonstrating IgE binding from allergic subjects to purified proteins.

Main Results:

  • The Allergen Nomenclature database (www.allergen.org) has grown to include approximately 880 proteins.
  • The Sub-Committee assigns official allergen names prior to publication, ensuring consistency.
  • Most journals require an official allergen name for publishing new allergen information.

Conclusions:

  • The WHO/IUIS Allergen Nomenclature Sub-Committee plays a crucial role in standardizing allergen identification and naming.
  • The database and review process facilitate consistent communication and research in allergology.
  • Ongoing efforts are necessary to adapt to advancements in 'omics' technologies and the discovery of new allergens.
