Give evidence for and describe the formation of heavier elements during star formation and evolution. SII/12PC-IIIa-2
Answers
Answer:
Heavy elements are formed in a supernova, a massive explosion of a star. ... Rather, a more massive isotope of the same element is produced. Elements higher than iron requires tremendous amount of energy to be formed. Thus, they were produced from a neutron capture reaction in a supernova.
Answer: The lightest components (hydrogen, helium, deuterium, lithium) were created in the Big bang nucleosynthesis. As per the Theory of the universe's origin, the temperatures in the early universe were high to such an extent that combination responses could happen. This brought about the arrangement of light components: hydrogen, deuterium, helium (two isotopes), lithium and follow measures of beryllium.
Atomic combination in stars changes over hydrogen into helium in all stars. In stars less enormous than the Sun, this is the main response that happens. In stars more enormous than the Sun (yet less huge than around 8 sun based masses), further responses that convert helium to carbon and oxygen occur in concurrent phases of heavenly advancement. In the extremely enormous stars, the response fasten keeps on delivering components like silicon to iron.
Components higher than iron can't be framed through combination as one needs to supply energy for the response to happen. In any case, we in all actuality do see components higher than iron around us. The response is supernovae. In a cosmic explosion blast, neutron catch responses occur (this isn't combination), prompting the development of weighty components. This is the justification for why it is said that a large portion of the stuff that we see around us come from stars and supernovae (the weighty components part). On the off chance that you delve into specialized subtleties, there are two cycles of neutron catch called fast interaction (r-process) and the rapid cycle (s-process), and these lead to development of various components.
