Describe how a proton found in a love content gas cloud (nebula subsequently found itself in an ingredient of lead on the primitive countrySupernova , which is the fusillade of a champ that expels stellar material with great force are the secrets to the reality of heavy metals such as calculate (Pb . occur is besot during supernova explosions . Other very heavy fragments are withal make during supernova explosions . Many of the heavier metals have very large nuclei so that they are very un unchanging ( alive(p) . They undergo hot free fall where they drive out proton or neutron , or a neutron in its nuclei decays into an electron and a proton . The process of radioactive decay makes un changeless heavy metals to incur more and more stable . Lead is not radioactive thusly it is stable and does not spontaneously dec ay into barge elements . Unstable heavy elements therefore decay over quantify until eventually they become Lead . For example , unstable element Uranium 238 decays over conviction resulting in a stable element : LeadSo how does proton find its appearing into the speck of Lead ? The solvent lies in the beginning of stars similar our solar system . like our solar system stars started from a cloud of heat content and break up . As the mass of the dust at the core increases to the size of a star , the pressure at the core crushes the piece to a very high dense material . imputable to the abundant pressure caused by gravity , the core becomes extremely hot that hydrogen fuses to helium . The fusion of 2 Proton and 2 Neutron produces helium and the light (photon ) that is emitted by burning star . So by and by the explosion and years of radioactive decay , the proton from the stars finds its way into the atom of a heavy metal called leadTo complete the move round of the proton , let us find out how it arrived int! o the primitive adult male .

Going back to the prayer of dust and cloud of hydrogen , the less dense particles that where not pulled into the core became the planets that circled around the sunshine . According to recent studies , radioisotope dating of meteorites suggests that planets formed in the solar System over shorter timescales than had been thought (Cameron 1 . Their results indicate that the cores of Vesta (where the meteorite originated , dismay and Earth all formed sooner after the establishment of the solar nebula than previous estimates had allowed . The said document further suggests a more realistic picture that th e earth s core underwent a continual core formation starting 29 one thousand thousand years ago If this is the case , the supernova that existed during the core formation contributed to the descent of the elements that existed on planet earth . There is even a possibility that the core of the solar system exploded when it collided with another(prenominal) collection of dust and dislodge the other planets , including the primitive earth . The explosion in the same manner produced the Lead from the categoric protonReferencesCameron , A . G .
