element ae is an element used in animation. It is also known as the ‘electronic affinity’, and it has some very interesting properties that can be useful for animation.
The ‘electronic affinity’, or ‘Eea’, of an element is the energy released per mole of atoms when the atom gains an electron. It is measured in kJ mol-1 and usually has a negative value.
Electron affinities vary greatly from element to element on the Periodic Table. The most positive values are found in elements that are nonmetals, especially chlorine and neon.
They are also higher for atoms that have anions with a greater stable charge than the neutral atom, such as fluorine.
Generally, ‘electronic affinity’ increases from row (period) to column on the periodic table before a new group has reached. This is because a new group has a filled valence shell and the added electrons are more stable.
Some atoms in groups 17 and 18 have a filled valence shell so they release more energy on gaining an electron than a group 1 atom. This is the basis for an important relationship called ‘Eea = -DE(attach)’ where ‘DE’ stands for ‘detach’ and ‘Eea’ represents a reversal of direction, that is, the electron capture requires more energy than the initial capture.
This ‘Eea’ relationship is used to predict the behavior of chemical reactions in which the atoms of an element attach or detach an electron from another atom. If an element’s ‘electronic affinity’ is high, it will be more likely to attract or detach an electron from a gaseous atom.
