Seleat the NeNa cycle. What is the identity of the catalyst-the isotope that begins the cycle? (tt is the lower-ieft isotope covered by the aigang pattern.) \begin{tabular}{l} mbgneslum-23 \\ magnesium-22. \\ neon-20 \\ sodimin-23 \\ \hline \end{tabular} First, be were that veu have selected the NeNa cyde. Next, recal that the y-axis, or proton mumber, determines the element ( 6 for carbon, 7 for nitrogen, etc.). Moanimhile, the sum of the xar ar W values determines the atomic mast number (e. 4 the " 12 in "carbon 122) (1) Seiect the NeNa cyde.
