   • multiscripted notation with optional arguments

     <math display="block">
       <mmultiscripts intent="isotope($base,$count)">
         <mi arg="base" intent="carbon">C</mi>
         <mrow></mrow>

   • also:

     <math display="block">
       <mmultiscripts intent="isotope($base, $count, $mass)">
         <mi arg="base" intent="carbon">C</mi>
         <mrow></mrow>
         <mrow></mrow>

8. positive-charge (1+, $Na^{+}$, "a $2^+$ ion")
9. negative-charge (1- , $O^{2-}$)
10. positive-or-negative-charge ($4±$)
11. oxidation-number (+2)
12. proton ($p^+$)

22. molar-gas-constant (R)
23. molar-volume ($V_m$)
24. heat-of-fusion ($H_f$)
25. pressure (P)
    • should $P_A$, $P_B$ (if fully annotated) be read pressure-cap-a, pressure-cap-b ?
    • similarly $M_A$, $M_B$ (if fully annotated) be read molar-mass-cap-a, molar-mass-cap-b ?
    • note $P_A = 1 \mathrm{k}\mathrm{Pa}$ is potentially confusing if both P are spoken "cap p", rather than "pressure-A is equal to one kilo pascal"

27. double-bond (=, ‖ :covalent-bond)
28. triple-bond (≡, :covalent-bond)

   • near-aliases are :ionic-formula, :empirical-formula
5. :chemical-equation
6. :system-of-equations
7. :lewis-diagram or :lewis-structure
