Late 18th century: from Triton.
A nucleus of a tritium atom, consisting of a proton and two neutrons.
- ‘Recent experimental data have shown that the same model systematically overpredicts the deuteron and triton yields observed at higher excitation energies up to 405 MeV.’
- ‘Protons, deuterons, and tritons would begin fusing with each other, releasing more energy, and initiating other fusion reactions among other hydrogen isotopes.’
- ‘The raw spectra of protons, deuterons, tritons and alpha particles were fitted with a three moving source prescription.’
1940s: from tritium + -on.
A minor sea god usually represented as a man with a fish's tail and carrying a trident and shell trumpet.
The largest satellite of Neptune, the seventh closest to the planet, discovered in 1846. It has a retrograde orbit, a thin nitrogen atmosphere, and a diameter of 1,678 miles (2,700 km)
