Which element’s atoms have the greatest average number of neutrons? tin (Sn) antimony (Sb) tellurium (Te) iodine (I) |

Answer» Number of neutrons of the elements can be calculated if the atomic number and mass number is known.As, Number of neutrons= Mass number Atomic numberFor Tin(SN), the mass number is 119 and atomic number is 50, thenNumber of neutrons=119-50=69For Antimony(Sb), the mass number is 122 and the atomic number is 51, thenNumber of neutrons=122-51=71For Tellurium(Te), the mass number is 128 and atomic number is 52,thenNumber of neutrons=128-52=76 Fro IODINE(I), the mass number is 127 ANDTHE atomic number is 53, thenNumber of neutrons=127-53=74 Since, the number of neutrons are largein Tellurium, therefore Tellurium have the GREATEST average number of neutrons. |
