Billions of years would pass before the photosynthetic microorganisms could eventually change the atmosphere’s composition.
WebHelium is an inert and harmless gas, so the particles are not dangerous in themselves, it is only because of the high speeds at which they are ejected from the nuclei that they become dangerous. At these high speeds they have enough energy to break bonds in matter or ionise atoms (knock electrons off), which is especially deleterious for living cells. Helium-4 is an unusually stable nucleus because its nucleons are arranged into complete shells. It was also formed in enormous quantities during Big Bang nucleosynthesis.
