Table Of Electron Affinity - The electron affinity (eea) of a molecule or an atom or is the amount of energy spent or released when an electron is added to a neutral atom or molecule in the gaseous state to form a negative ion.. The amount of energy released when an electron is added to atom) for most of chemical elements. Electron affinity generally increases from bottom to top within a group (that is, it goes to larger negative numbers), and increases from left to right within a period. Quizlet is the easiest way to study, practise and master what you're learning. Many species have anions that are not bound with respect to a free electron and the neutral species, in which case the calculations may give results that are not meaningful. Electron affinity is the amount of energy required to detach one electron from a negatively charged ion of an atom or molecule.
Electron affinity tends to increase across a period. This is due to their atoms have stable ns2 np6 configuration in their shell. Electron affinity decrease down the groups and increases from left to right across periods of a periodic table. Electron affinity increases towards the top of the periodic table and towards the right.

Electron Affinity for all the elements in the Periodic Table from periodictable.com Results of electron affinity calculations are very dependent on the basis set. Electron affinity follows a trend on the periodic table. Electron affinity (ea) or electron gain enthalpy or simply affinity in the periodic table defines the amount of energy released when an electron is added to an isolated neutral gaseous atom in its lowest energy level (ground state) to produce an anion. Each value has a full citation identifying its source. Quizlet is the easiest way to study, practise and master what you're learning. The amount of energy released when an electron is added to atom) for most of chemical elements. Electron affinity can be defined in two equivalent ways. X(g) + e− → x−(g) + energy.
Interactive periodic table showing names, electrons, and oxidation states.
We have talked about atomic structure, electronic configurations, size of the atoms and ionization energy. X(g) + e− → x−(g) + energy. In the use of electron affinity data, it is essential to keep track of the sign. The first electron affinity of elements in the periodic table increases across the period and decreases down the group. Electron affinity is defined as the change in energy (in kj/mole) of a neutral atom (in the gaseous phase) when an electron is added to the atom to form a negative ion. Its value generally increases on moving from left to right in a period in the periodic table to decrease in atomic size with the increase of nuclear charge. Results of electron affinity calculations are very dependent on the basis set. This is due to their atoms have stable ns2 np6 configuration in their shell. This page deals with the electron affinity as a property of isolated atoms or molecules (i.e. The resultant chemical reaction produces an exothermic as we go from top to bottom across the periodic table, the electronic affinity decreases. Electron affinity of the elements. Interactive periodic table showing names, electrons, and oxidation states. Electron affinity generally increases from bottom to top within a group (that is, it goes to larger negative numbers), and increases from left to right within a period.
