WebPhotons with insufficient energy can hit metal, yet won't knock any electrons loose. Photons that exceed a threshold energy usually do knock the electrons loose, however, as the … WebDec 23, 2015 · Photons can be regarded as stable particles depending on perspective. In the Sun's core hydrogen atoms break down into a mixed plasma which includes protons and deuterium atoms. If these collide they form a helium-3 nucleus and a gamma ray is released. The gamma ray is a highly energized photon.
