Från Wikipedia, den fria encyklopedin. Den elektronaffinitet ( E ea ) av en atom eller molekyl definieras som Organic field-effect transistors and solar cells using novel high electron-affinity conjugated copolymers based on alkylbenzotriazole and benzothiadiazole.

Difference Between Electronegativity And Electron Affinity For PDF Notes and best Assignments visit @ http://physicswallahalakhpandey.com/Live Classes, Video Lectures, Test Series, Lecturewise notes, topicwise DPP, Definition of electron affinity Electron affinity is the affinity of an element to an electron. This is measured by the energy released when an element in its gaseous state accepts an electron to form an anion. So this is an exothermic reaction. They are expressed in KJ mol-1. Electron affinity, Electronegativity, Ionization energy 1. Electron affinity Definition: The energy released when an electron is added to a gaseous atom which is in its ground state to form a gaseous negative ion is defined as the first electron affinity. The symbol is EA, and the unit is kJ/mol.

The electron affinityof an element is the energy given off when a neutral atomin the gas phase gains an extra electron to form a negatively charged ion. Afluorine atom in the gas phase, for example, gives off energy when it gains an electron toform a fluoride ion.

This occurs because of the same subshell rule that governs ionization energies. Example: Since a half-filled "p" subshell is more stable, carbon has a greater affinity for an electron than nitrogen.

Each value has a full citation identifying its source. The integrated unit conversion Electron affinity, the oft-forgotten — yet essential – periodic property. Geoff Rayner-Canham, Grenfell Campus, Memorial University, Corner Brook NL. Share :. 1st Electron Affinity is negative because energy is given out because electrons are attracted to the nucleus by effective nuclear charge.

Atom: English translation, definition, meaning, synonyms

There are general trends in electron affinity across and down the periodic table of elements. Electron affinity Third in importance for bond formation after size and ionization energy is the energy change accompanying the attachment of electrons to a neutral atom.
