) Sketch a graph of the variation in neutron number with atomic number for elements with stable nuclei. Plot on the -axis against on the -axis and use a single line to show the general trend. Extend your -axis to 92. Shade regions on the same graph to show where unstable radionuclides may be found that decay through 1. Alpha particle emission Beta -ve particle emission Beta postive particle emission

Which of the following is not an important assumption of the radiometric age dating method? Decay occurs at a constant rate The concentration of parent isotopes starts at zero The concentration of daughter isotopes starts at zero Decay occurs in a closed system
there are curly ustable nuclides with 6. 29p and 33p are both radioactive. One decays by beta emission and the other by positron emission. Determine the mode of decay for each and explain your reasoning.
Indicate the LARGER quantity. If the two quantities are equal, write “equal”, and if there is not enough information to determine which is larger, state “not enough info. Explain your reasoning. YOU MAY NOT USE A CALCULATOR FOR THIS PROBLEM. Use your estimation skills!b) The energy produced when 10.0 mole of 14C is combusted orThe energy produced when 1.0 mole of14C decays via beta decay.
