Nadion particles are the primary nuclear based energy source for all of Pulse phaser weapons used by the Federation from the majority of the 22nd to 25th century.
Nadions are an artificially-generated atomic particle. Nadions are capable of liberating atomic nuclei, disrupting nuclear forces. Among other uses, phasers and disruptors of some other species produced superheated beams of nadions when fired.
Nadions also had some gravitational repulsion/attraction properties as many Starfleet ships were equipped with Nadion emitters that acted as docking apparatuses to star bases or stations.
