(a)
Interpretation:
Probable mode of decay for the given radioactive isotope has to be predicted and equation for the given radioactive isotope has to be written.
Concept Introduction:
In this radioactive decay process the unstable isotopes loses their energy by emitting radiation. It is converted to stable isotopes. The emitting radiations are positron emission, gamma emission, beta emission and electron capture.
In beta decay, there will be a lose of electron from nucleus (neutron turns into proton): there will be no change in mass number and
(b)
Interpretation:
Probable mode of decay for the given radioactive isotope has to be predicted and equation for the given radioactive isotope has to be written.
Concept Introduction:
In this radioactive decay process the unstable isotopes loses their energy by emitting radiation. It is converted to stable isotopes. The emitting radiations are positron emission, gamma emission, beta emission and electron capture.
In alpha decay, there will be lose of
(c)
Interpretation:
Probable mode of decay for the given radioactive isotope has to be predicted and equation for the given radioactive isotope has to be written.
Concept Introduction:
In this radioactive decay process the unstable isotopes loses their energy by emitting radiation. It is converted to stable isotopes. The emitting radiations are positron emission, gamma emission, beta emission and electron capture.
In beta decay, there will be a lose of electron from nucleus (neutron turns into proton): there will be no change in mass number and atomic number increases by one.
(d)
Interpretation:
Probable mode of decay for the given radioactive isotope has to be predicted and equation for the given radioactive isotope has to be written.
Concept Introduction:
In this radioactive decay process the unstable isotopes loses their energy by emitting radiation. It is converted to stable isotopes. The emitting radiations are positron emission, gamma emission, beta emission and electron capture.
A positron is like an electron but it has a positive charge.
During a positron emission a proton changes into a neutron and the excess positive charge is emitted.

(Note: it's not equal to the difference in chemical shifts.) Round your answer to 2 significant digits, and be sure it has an appropriate unit symbol. = O O a will shift left, c will shift right. O a will shift right, c will shift left. a and c will both shift left, with more space between them. Suppose a new spectrum is taken with a 500 MHz spectrometer. What will be true about this new spectrum? O a and c will both shift left, with less space between them. O a and c will both shift right, with more space between them.
