Z+
(Z+)
(symbol for ion or ion charge)
Z+ (and the similar Z+, in both cases,
the letter "Z" and a plus sign) are used sometimes regarding positive
ions, i.e., atoms or molecules missing one or more electrons,
giving it a positive charge.
Ways in which they are used:
- Z+ is used as the superscript of a chemical formula, Z indicating some unspecified positive number, e.g., CZ+ meaning either C1+ or C2+, etc. for ionized carbon that is positively charged, but not specifying the charge amount.
- Z+ (i.e., "Z" with "+" as a superscript) uses "Z" to indicate an unspecified element, with Z+ representing that element with a positive charge typically meaning a charge of +1 (He+, C+, etc.).
Z+ may sometimes be intended to mean singly ionized,
but possibly sometimes that assumption is not intended (i.e., C2+,
O3+, etc.).
However, the electrical charge can specified explicitly, e.g.,
Z++ or Z2+.
