3. The Oath of Feanor Chain Reaction
Initiation: The reaction begins with a Feanor element losing three electrons to form a free radical. The presence of both a Melkor element as well as the remains of a Finwe element are necessary in order to initiate the reaction. The absence of any Vala elements also allows the reaction to occur.
Propagation: The Feanor free radical will react with almost any element or molecule it comes into contact with. However, it has a particular attraction to Sons of Feanor molecules and other Elf molecules and elements. A favorable collision between the Feanor free radical and one of these molecules will result in the formation of a new free radical and an even less stable Feanor. This new free radical will then react with other elf molecules, transforming them into free radicals and so propagating the reaction.
Curufin and Celegorm molecules are particularly susceptible to Feanor free radicals, as are Maedhros +1 molecules. Maglor molecules in the vicinity of Maedhros free radicals may also become radicalized, although they tend to stabilize once away from other molecules.
While the interaction between a free radical and a neutral molecule almost always results in the conversion of the neutral molecule into a free radical, if a large number of free radical Noldor molecules collide with neutral Teleri molecules, the Teleri molecules may break apart due to the collision. The massive amounts of energy released from this fission will repulse all Valar elements and cause some Noldor free radicals to stabilize and attempt to move back towards the Valar.
Termination: The reaction terminates when two Noldor free radicals collide and form product. However, due to the inherent instability of the free radicals, any collision between them results as often as not in the complete destruction of the molecules. Indeed, even when product is formed in the collision, it is highly radioactive and toxic, earning it the nickname the "Doom of the Noldor" or "Noldolante" molecule.
Interestingly, both the Maedhros and Maglor free radicals avoid this destructive collision. The Maedhros free radical terminates by colliding with the wall of the reaction vessel. The Maglor free radical is repulsed by other molecules and often appears to disappear from the reaction vessel. As of yet, there is no way to detect the presence of a Maglor free radical after it has left the vicinity of other molecules.
