physical sci - 2

• big bang theory - describes as the origin of light element which started from singularity
• big bang theory - among the proposed explanation on how the universe began and currently accepted theory
• nucleosynthesis - explains how new atomic nucleus are formed from nucleus preceding from the new ones
• stellar nucleosynthesis - birth of elements through nuclear fusion that takes with stars
• stellar nucleosynthesis - the process by which the natural abundance of the chemical elements within stars vary due to nuclear fusion reactions
• nuclear fusion - it is how elements hydrogen, helium and small amounts of lithium, and beryllium were formed
• nuclear fusion - a process by which neutron and protons combine together to form a new atom
• nuclear fusion - an extremely high energy and temperature of the universe
• triple alpha process - is a set nuclear fusion to which three helium-4 atoms are transformed into carbon
• c-n-o cycle - it is the catalytic cycle
• c-n-o cycle - one of two known sets of fusion reactions by which stars convert hydrogen to a helium in a larger main-sequence star
• alpha ladder - one of two class of nuclear fusion reactions by which stars convert helium into heavier elements
• supernova - it is where all the elements heavier than iron formed
• supernova nucleosynthesis - a massive explosion of a star
• supernova nucleosynthesis - a nucleosynthesis of chemical elements in supernova explosions
• supernova nucleosynthesis - neutron capture reaction takes place, leading to the information of heat elements
• c burning shell - a set of nuclear fusion reaction that take place in the cores of massive stars that combines carbon into other elements
• o burning shell - set of nuclear fusion reaction that needs up lighter elements in their core
• rapid neutron capture process - involves rapid capture of neutrons by the atom
• slow neutron capture process - involving slow neutron capture in red giants
• lighter elements - formed during the big bang theory
• heavy elements - formed after lighter elements
