Like how did these elements came into existence.

Cosmology question??

Dec 30th, 2014

Adding extra protons and neurons to an atom, makes atom to increase its atomic number to become a heavier element.

This achieved by two main processes: the s-process and the r-process, which are both neutron capture processes that are differentiated by their speed relative beta-decay of neutron rich isotopes.

Both are end-of-stellar-life processes with the S-process probably happening in the giant stages of very heavy stars and the r-process probably happening in core-collapse supernovas.

Hope it Helps!
