Less stable isotope from the list has to be predicted. Concept Introduction: Nuclear stability means that the nucleus is stable meaning that it does not spontaneously emit any kind of radioactivity. Nuclear stability can be explained based on neutron proton ratio (n/p) in the nucleus. For a stable atoms having low atomic number , n/p ratio is close to 1. When atomic number increases n/p becomes greater than 1. General rules for predicting the nuclear stability is given below, If the nucleus contains 2, 8,20,50,82 or 126 protons or neutrons, then they are generally considered as stable than the nuclei that do not possess these numbers. If the nuclei has even number of both protons and neutrons, then they are considered as stable as those with odd number of these particles. All isotopes of elements with atomic number higher than 83 are radioactive.

A pdf file of your hand drawn, stepwise mechanisms for the reactions. For each reaction in the assignment, you must write each mechanism three times (there are 10 reactions, so 30 mechanisms). (A) do the work on a tablet and save as a pdf., it is expected to write each mechanism out and NOT copy and paste the mechanism after writing it just once. Everything should be drawn out stepwise and every bond that is formed and broken in the process of the reaction, and is expected to see all relevant lone pair electrons and curved arrows.
