Vedclass · Answer

(C) Isotones are species that have the same number of neutrons but different atomic numbers.For $_{37}Rb^{86}$,the number of neutrons is $N = A - Z = 86 - 37 = 49$.Now,let us calculate the number of neutrons for each option:$A) _{36}Kr^{84}: N = 84 - 36 = 48$$B) _{37}Rb^{85}: N = 85 - 37 = 48$$C) _{38}Sr^{87}: N = 87 - 38 = 49$$D) _{39}Y^{89}: N = 89 - 39 = 50$Since $_{38}Sr^{87}$ has $49$ neutrons,it is isotonic with $_{37}Rb^{86}$.

Which of the following species is isotonic with $_{37}Rb^{86}$?
