Proton

A tiny positively charged subatomic particle shown as a compact smooth sphere in a clean educational physics-icon style. The proton is usually bright red, pink, red-orange, or other warm tones, with a glossy highlight or subtle shading and sometimes a faint glow. A clear white plus sign is centered on the sphere or placed immediately nearby to indicate positive charge. The particle is isolated, simple, bold, and diagram-ready, like a textbook scientific clipart symbol or a hydrogen nucleus with no surrounding electron shell. Use consistent thin outlines, soft glossy shading, and minimal detail.
