Concept explainers
Interpretation:
The number of protons and neutrons with the help of the symbol of nuclide is to be determined.
Concept Introduction:
To understand the radioactivity of heavy
The notation of elements is written as
The atomic number and proton number in element is same.
The mass number is the sum of number of neutrons and number of protons.

- Write the nuclide notation, including charge if applicable, for atoms with the following characteristics: (a) 25 protons, 20 neutrons, 24 electrons. (b) 45 protons, 24 neutrons, 43 electrons. (c) 53 protons, 89 neutrons, 54 electrons. (d) 97 protons, 146 neutrons, 97 electronsarrow_forward14C is used in carbon dating of artifacts. Determine the number of protons and neutrons in 14C.arrow_forward2.10 Which isotope in each pair contains more neutrons? (A) 35Cl or 33S, (b) 19F or 19Ne, (c) 63Cu or 65Zn, (d) 126I or 127Tearrow_forward
- Write the following isotopes in nuclide notation (E.g., " C614 ")? (a) oxygen-14. (b) copper-70. (c) tantalum-175. (d) francium-217arrow_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
