Abundances of ions, electrons, and grains as a function of density for all the disk particles at the final time of the simulations (5.83 × 104 yr). The set ofinitial abundances A is used. Following Umebayashi & Nakano (1990) and Marchand et al. (2016), M+ represents the metallic ions (i.e., all the ions that include Si, Fe, Mg, and Na). m+ includes all the other positively charged ions (containing H, C, N, O, S, and P atoms) except for H+, H, He+, CH, and C2 H, which are shown separately. m represents all the anions (containing H, C, N, O, and S atoms) except for H.
