Anion \An"i*on\, n. [Gr. ?, neut. ?, p. pr. of ? to go up; ? up

An electro-negative atom or group of atoms, or the element
which, in electro-chemical decompositions, is evolved at the
anode; -- opposed to {cation}. --Faraday.

  • Anion Gap Blood Test: Results and Ranges - WebMD
    The anion gap test is the calculated difference between positively and negatively charged electrolytes in your blood to determine if your blood is too acidic or not acidic enough (too base)
  • Anion Gap: Low, Normal High Levels + Causes, Symptoms
    The anion gap is a value that represents the difference between positively charged ions (cations) and negatively charged ions (anions) in the blood The anion gap cannot be directly measured, instead, it is calculated from the results of an electrolyte panel, another type of blood test
  • Cations and Anions: Definitions, Examples, and Differences
    Cations and anions are the two types of ions Ions have an imbalance of electrical charge, meaning they contain different numbers of protons and electrons Cation have a positive electrical charge and have more protons than electrons Anions have a negative electrical charge and have more electrons than protons
  • ANION Definition Meaning - Merriam-Webster
    The meaning of ANION is the ion in an electrolyzed solution that migrates to the anode; broadly : a negatively charged ion
  • Anion Chemistry Glossary Definition and Examples - ThoughtCo
    The word anion [AN-aye-un] was proposed by English polymath the Rev William Whewell in 1834, from the Greek anion, or "thing going up," referring to the movement of anions during electrolysis Physicist Michael Faraday was the first person to use the term in a publication
  • Cation vs Anion: Definition, Chart and the Periodic Table
    What is an anion? An anion has more electrons than protons, consequently giving it a net negative charge For an anion to form, one or more electrons must be gained, typically pulled away from other atoms with a weaker affinity for them
  • Anion - Simple English Wikipedia, the free encyclopedia
    Anions are atoms or radicals (groups of atoms), that have gained electrons Since they now have more electrons than protons, anions have a negative charge For example, chloride ions Cl- , bromide Br- , iodide I- These are monovalent anions, meaning they have a valency (combining capacity) with only one ion of hydrogen
  • Anion | chemistry | Britannica
    Anion, atom or group of atoms carrying a negative electric charge See
  • Anion - Encyclopedia. com
    An anion is a negatively charged atom or group of atoms Anions are attracted to the anode , or positive electrode, in an electrolytic cell Some common anions are the hydroxide ion (OH-), the chloride ion (Cl-), the nitrate ion (NO3- ), and the bicarbonate ion (HCO3- )
  • 7. 4: Anions - Chemistry LibreTexts
    Anions are negative ions that are formed when a nonmetal atom gains one or more electrons Anions are so named because they are attracted to the anode (positive field) in an electrical field Atoms typically gain electrons so that they will have the electron configuration of a noble gas
