Problem

Study the data given below and answer the questions that follow. (i) A nuclide

_{38}^{90}\mathrm{Sr}

is found in the fission products of uranium. Calculate its neutron number. (ii) Another nuclide in the same sample is

_{36}^{90}\mathrm{Kr}

. State the nuclear relationship that exists between

_{38}^{90}\mathrm{Sr}

and

_{36}^{90}\mathrm{Kr}

. (iii) Determine the nuclide symbol of the nucleus that has the same neutron number as

_{38}^{90}\mathrm{Sr}

but an atomic number of 40. Identify the relationship between this new nuclide and

_{38}^{90}\mathrm{Sr}
