Metal ion

A single generic positively charged metal ion shown in simplified diagram style as a small smooth spherical icon or metallic-colored circle. The sphere is clean, compact, and centered, typically silver-gray, blue-gray, pale blue, purple, green, or another element-coded metallic hue, with a subtle highlight. A clearly visible positive charge marker appears beside it or as a small superscript label such as +, 2+, or 3+. Some variants may include an element symbol on or beside the sphere. No surrounding ligands or other structures are present, making it suitable as a standalone dissolved metal cation or coordination-center symbol.
