Radiation
is spontaneously emitted from hydrogen-3 nuclei, but radiation is not
spontaneously emitted from hydrogen-1 nuclei or hydrogen-2 nuclei. Which hydrogen
nuclei are stable
The hydrogen nuclei that are stable are hydrogen-1 nuclei
or hydrogen-2 nuclei because radiation is not spontaneously emitted from them. Only
the hydrogen – 3 nuclei is spontaneously emitted by radiation.
