What happens during nuclear decay reactions? Check all that apply.    Radiation is emitted.    New and more stable nuclei form as a result of nuclear decay.    Explosions occur.    The excess matter and/or energy present in unstable atoms in unstable atoms is given off.

If the amount of radioactive carbon in a fossil sample is too small to be measurable, you   can't use radioactive dating to determine its age   can bombard it with neutrons to determine its age   can use radioactive dating on the surrounding rock   can bombard it with electrons to determine to determine its age

The first two particles emitted in the decay series for Actinium (Ac)-227 are beta and then alpha. What is the resulting isotope (element and mass) at this point in the series? Represent all work with nuclear equations. all work and your final answer (given in nuclear notation).

In the following equation, what particle or type of radiation decay is needed in order to balance it? 147 61Pm ´61PM 147 62Sm + ?
