- The following table gives the number of protons and neutrons in the nuclei of various atoms. Which atom is the isotope of atom A? Which atom has the same mass number as atom A? Protons Neutrons Atom A 32 39 Atom B 33 38 Atom C 38 50 Atom D 32 38arrow_forwardObtain the fractional abundances for the two naturally occurring isotopes of europium. The masses of the isotopes are 151Eu, 150.9196 amu; 153Eu, 152.9209 amu. The atomic weight is 151.9641 amu.arrow_forwardGive the complete symbol (XZA), including atomic number and mass number, of (a) a nickel atom with 31 neutrons, and (b) a tungsten atom with 110 neutrons.arrow_forward
- Silicon (averageatomicmass=28.0855amu) has three isotopes. Their masses are 27.9769 amu, 28.9765 amu, and 29.9738 amu. The abundance of the heaviest isotope is 2.96%. Estimate the abundances of the first two isotopes.arrow_forwardDefine mass number. What is the difference between mass number and atomic mass?arrow_forwardDuring nuclear decay a 238U atom can break apart into a helium-4 atom and one other atom. Assuming that no subatomic particles are destroyed during this decay process, what is the other element produced?arrow_forward
