There isn't a universally accepted single symbol for plasma in chemical equations. While plasma is a state of matter, unlike solids, liquids, and gases, it's rarely used in standard chemical notation.
Symbol Usage in Specific Contexts
-
In rare instances where plasma is used in an equation,
(p)is sometimes employed as a symbol. This is not a standardized symbol, however, and its use is highly context-dependent. ([Reference: Wikipedia - State of matter, various forum discussions]) -
Graphical Representations: Various icons and symbols are used to represent plasma in different contexts, such as in software interfaces (like the KDE Plasma desktop environment) or to denote specific plasma welding processes. These are not chemical symbols, but rather visual cues. ([Reference: Flaticon - Plasma Icons & Symbols, KDE Discuss forum, arcraftplasma.com - Weld and Welding Symbols])

In other fields, such as clinical pharmacokinetics, specific symbols may be used to denote plasma (e.g., within tables and notations indicating specific measured concentrations), but these aren't universally applicable chemical symbols. ([Reference: Springer - Clinical Pharmacokinetics Preferred Symbols])
Therefore, while a specific symbol for plasma is lacking in mainstream chemical notation, the occasional use of (p) exists within certain limited applications.
