The life span of atomic hydrogen is
Answers
If you keep an electron and a proton together as hydrogen atom in isolation somewhere in the deep vacuum of space, nothing much will happen to it. Until it hits another atom or a photon: then the electron and the proton could be separated. Does that count as end of life? Here on earth, a separate hydrogen atom will encounter other atoms all the time, and it will be quickly take part in chemical reactions. Does that mean its end of life? A hydrogen atom in a molecule is sharing electrons. You can not even distinguish or follow the individual electrons according to quantum theory. Does that mean its end of life? A hydrogen nucleus in the plasma of the sun is swimming in a sea of other protons and electrons. Do you still call it a hydrogen atom? Then its true end of life may be near, because in the fusion reactor that we call our sun hydrogen is combined into helium nuclei.
