Discuss the implications of neutron-to-proton ratios in relation to isotopic stability. Why might certain isotopes be viable for medical imaging, while others are not?
💡 Hint: Consider the long-term effects of stability and decay.
Calculate the average atomic mass for an element with three isotopes: Isotope A (mass 10.0129 u, abundance 20%), Isotope B (mass 11.0093 u, abundance 50%), Isotope C (mass 12.0000 u, abundance 30%).
💡 Hint: Convert percentages to fractions by dividing by 100.
