The electron affinity (EA) of an element is the energy change that occurs when an electron is added to a gaseous atom to give an anion. In general, elements with the most negative electron affinities (the highest affinity for an added electron) are those with the smallest size and highest ionization energies and are located in the upper right corner of the periodic table.

26 Oct 2012 Specific patterns of certain elemental characteristics are present in the periodic table. The tendencies of these patterns increase or decrease as

There are 118 elements in the periodic table. Each element has a unique atomic structure that is influenced by its electronic configuration, which is the distribution of electrons across different orbitals of an atom. The electron affinity of an element is the energy change which accompanies the addition of an electron to an atom in the gas phase to produce a negatively charged anion: X (g) + e- ® X - (g) Electron affinities are usually negative values, since energy is usually released (an exothermic energy change) when an electron is added to a neutral atom. 2020-02-27 · An atom with a very negative electron affinity and a high ionization energy both attracts electrons from other atoms and resists having its electrons attracted away; therefore it is highly electronegative. Electronegativity values can be based on a variety of properties, not just ionization energy and electron affinity.

There are general trends in electron affinity across and down the periodic table of elements. The Electron Affinity trend, like other trends in the periodic table, reflects the fact that electron affinity follows a predictable trend as one reads the periodic table. In this case, electron affinity increases from top to bottom and left to right. The electron affinity is the energy change when an atom gains electrons. The convention is that the higher or more positive the electron affinity value, the more readily the atom accepts an electron.

Electron affinity decreases moving down a column and increases moving left to right across a row of the periodic table. The value cited for an atom's electron affinity is the energy gained when an electron is added or the energy lost when an electron is removed from a single-charged anion.

The electron affinity of an element is the energy change which accompanies the addition of an electron to an atom in the gas phase to produce a negatively

The following periodic table shows the known electron affinity data for the elements. The values are confined to the main group elements because the transition Variation of Electron Affinity in the Periodic Table. When an electron is added to an isolated gaseous neutral atom to form an anion, an amount of energy is Electron affinity varies diagonally across the periodic table.

This is because going from left to right and bottom to top, the atomic radius decreases so it is easier for the nucleus to attract negative electrons.
