Question:Cobalt–60 and iodine–131 are radioactive isotopes commonly used in nuclear medicine. How many protons,neutrons, and electrons are in atoms of these isotopes? Write the complete electron configuration for each isotope.
Give an example of an atom whose size is smaller than fluorine.
Question:49. Using complete subshell notation (1s22s22p6, and so forth), predict the electron configuration of each of the
following atoms:
(a) N
(b) Si
(c) Fe
(d) Te
(e) Tb
Identify the atoms from the electron configurations given:
(a)\(\left( {{\bf{Ar}}} \right){\bf{4}}{{\bf{s}}^{\bf{2}}}{\bf{3}}{{\bf{d}}^{\bf{5}}}\)
(b)\(\left( {{\bf{Kr}}} \right){\bf{5}}{{\bf{s}}^{\bf{2}}}{\bf{4}}{{\bf{d}}^{{\bf{10}}}}{\bf{5}}{{\bf{p}}^{\bf{6}}}\)
