Describe how a proton found in a catch fire content gas cloud (nebula subsequently found itself in an ingredient of lead on the primitive countrySupernova , which is the fit of a champ that expels stellar material with great force are the secrets to the reality of heavy metals such as make it (Pb . use up is besot during supernova explosions . Other very heavy fragments are too make during supernova explosions . Many of the heavier metals have very large nuclei so that they are very un unchanging ( piquant . They undergo hot disintegrate 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 stable heavy metals to incur more and more stable . Lead is non radioactive indeed it is stable and does not spontaneously decay in to barge elements . Unstable heavy elements therefore decay over quantify until eventually they become Lead . For example , unstable element Uranium 238 decays over beat resulting in a stable element : LeadSo how does proton find its carriage into the blood corpuscle of Lead ? The solvent lies in the beginning of stars want 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 great pressure caused by gravity , the core becomes extremely hot that henry fuses to helium . The fusion of 2 Proton and 2 Neutron produces helium and the light (photon ) that is emitted by burning star . So later on 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 or so of the proton , le t us find out how it arrived into the primit! ive mankind .

Going back to the sight of dust and cloud of hydrogen , the less dense particles that where not pulled into the core became the planets that circled around the cheerfulness . 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 , infect and Earth all formed sooner after the scheme of the solar nebula than previous estimates had allowed . The said document further suggests a more realistic picture that the earth s core und erwent a continual core formation starting 29 trillion years ago If this is the case , the supernova that existed during the core formation contributed to the personal line of credit 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 .
