Interpretation: The symbol corresponding to each isotope in the given table is to be determined; also the isotope which is unstable, one which has magic number of protons and neutrons and one which yield potassium-39 after proton emission is to be determined.
Concept Introduction: The symbol of the given isotope is determined by the
The unstable isotope is the isotope which has least half life.
The magic numbers are
The isotope which releases potassium-39 on positron emission must have mas number greater than 39.
(a)
To determine: The symbols of the each of the given isotopes.
Step 1:
To determine: The symbol of the given isotope.
Step 2:
To determine: The symbol of the given isotope.
Step 3:
To determine: The symbol of the given isotope.
Step 4:
To determine: The symbol of the given isotope.
(b)
To determine: The isotope which is most likely to be unstable out of the given isotopes.
(c)
To determine: The isotopes which contain magic number of neutrons and protons out of the given isotopes.
(d)
To determine: The isotope which yields potassium-39 after proton emission.
