Z+ has different usages relating
to positive Ions, i.e., atoms or molecules missing
one or more electrons, giving it a positive charge.
Ways in which it is used:
- "Z" can be taken as a variable for an unspecified element, with Z+ representing some element with a positive charge typically meaning a charge of +1 (He+, C+), but possibly an unspecified positive number (He+, C2+).
- Z+ can be the superscript of a chemical formula indicating some unspecified positive number, e.g., CZ+ meaning either C1+ or C2+, etc. for positively ionized Carbon of some positive charge.
