Concept explainers
(a)
Interpretation:
More stable isotope from the list has to be predicted.
Concept Introduction:
Nuclear stability means that the nucleus is stable meaning that it does not spontaneously emit any kind of radioactivity.
Nuclear stability can be explained based on neutron proton ratio (n/p) in the nucleus.
For a stable atoms having low
As the number of stable isotopes increases, stability of the element increases.
(b)
Interpretation:
More stable isotope from the list has to be predicted.
Concept Introduction:
Nuclear stability means that the nucleus is stable meaning that it does not spontaneously emit any kind of radioactivity.
Nuclear stability can be explained based on neutron proton ratio (n/p) in the nucleus.
For a stable atoms having low atomic number, n/p ratio is close to 1. When atomic number increases n/p becomes greater than 1.
As the number of stable isotopes increases, stability of the element increases.
(c)

- 2.10 Which isotope in each pair contains more neutrons? (A) 35Cl or 33S, (b) 19F or 19Ne, (c) 63Cu or 65Zn, (d) 126I or 127Tearrow_forwardFor each pair of elements listed, predict which one has more stable isotopes. (a) Ni or Cu (b) Se or Sb (c) Cd or Auarrow_forward2.86 For some uses, the relative abundance of isotopes must be manipulated. For example, a medical technique called boron neutron capture therapy needs a higher fraction of 10B than occurs naturally to achieve its best efficiency. What would happen to the atomic weight of a sample of boron that had been enriched in 10B? Explain your answer in terms of the concept of a weighted average.arrow_forward
- The atomic masses of hydrogen-2 (deuterium), helium-4, and lithium-6 are 2.014102 amu, 4.002602 amu, and 6.0151228 amu, respectively. For each isotope, calculate (a) the nuclear mass,arrow_forwardThe carbon isotope 11 6C undergoes b+ (positron) decay. The atomic mass of 11 6C is 11.011433 u. (a) How many protons and how many neutrons are in the daughter nucleus produced by this decay? (b) How much energy, in MeV, is released in the decay of one 11 6C nucleus?arrow_forwardThe isotope of plutonium used for nuclear fission is 239Pu.Determine (a) the ratio of the number of neutrons in a239Pu nucleus to the number of protons, and (b) the number of electrons in a single plutonium atom.arrow_forward
- Natural uranium consists almost entirely of 238U. To operate a nuclear power reactor, the fuel must be enriched in a lighter fissionable isotope, 235U. If the average molar mass of uranium in a reactor is 236.2, what percent of the fuel consists of the lighter isotope? Assume that the masses of the two isotopes are exactly 235 and 238 amu.arrow_forward"How do the isotopes of argon, Ar-36, Ar-38, and Ar-40, differ from each other?

- 203.) The naturally occurring isotope rubidium-87 decays by beta emission to strontium-87. This decay is the basis of a method for determining the ages of rocks. A sample of rock contains 122.0 μg^87 Rb and 6.1 μg^87 Sr . What is the age of the rock? The half-life of rubidium-87 is 4.8x10^10 y. There was no strontium-87 in the rock initially.

In addition to gamma emission, what is the mod iodine-131 ?arrow_forwardGiven the number of protons and neutrons in the nucleus of the given elements, make a diagram on how thenucleus was fused with another nucleus (by chance) to form heavier elements such as Cr, Ni, Fe. You maystart with Hydrogen or Helium Burning. You may also fuse the elements with Hydrogen (1), He (2), Li (3), andBe (4).
