(a)
Interpretation:
Mass defect of
Concept Introduction:
Neutrons and protons are collectively called nucleons. Sum of masses of nucleons is always greater than that of atomic nucleus. Difference between mass of neutrons and protons and that of nucleus is known as mass defect.
(b)
Interpretation:
Binding energy of
Concept Introduction:
Binding energy is energy that is equal to difference in mass. It is energy required to break nucleus into its constituent neutrons and protons. It is directly related to stability of atomic nucleus. High binding energies are characteristics of elements with intermediate atomic masses.

- For each pair of elements listed, predict which one has more stable isotopes. (a) Ni or Cu (b) Se or Sb (c) Cd or Auarrow_forward. The element zinc in nature consists of five isotopes with higher than0.5% natural abundances, with mass numbers 64, 66, 67, 68, and 70. Write the nuclear symbol for each of these isotopes. How many protons does each contain? How many neutrons does each contain?arrow_forwardThe following nuclei do not lie in the band of stability. How would they be expected to decay? Explain your answer.. (a) P1534 (b) U92239 (c) C2038a (d) H13 (e) P94245uarrow_forward
- 9-14 Write the symbol for a nucleus with the following components: (a) 9 protons and 10 neutrons (b) 15 protons and 17 neutrons (c) 37 protons and 50 neutronsarrow_forwardPlutonium was detected in trace amounts in natural uranium deposits by Glenn Seaborg and his associates in 1941. They proposed that the source of this 239Pu was the capture of neutrons by 238U nuclei. Why is this plutonium not likely to have been trapped at the time the solar system formed 4.7109 years ago?arrow_forward
