Which sequence is an example of radioactive decay? the nuclei of two hydrogen atoms fuse together, forming a helium nuclide. a calcium atom gives its electrons to two fluorine atoms, forming a formula unit of calcium fluoride. a polonium isotope becomes a lead isotope when the polonium nuclide emits two protons and two neutrons. energy from an electric current splits a water molecule into two hydrogen atoms and one oxygen atom.
