Pp chain

A compact schematic icon of the proton-proton fusion chain, shown as a sequence of small atomic nuclei or particle circles connected by short arrows. The chain begins with hydrogen nuclei or proton spheres and proceeds stepwise toward a brighter helium nucleus at the end. The particles are rendered as small glowing circles in scientific diagram colors such as pale blue, red, white, or pink for the starting nuclei, with the final helium product highlighted in brighter yellow-white or golden tones. Clean clipart-like schematic style, with thin connecting lines or arrows and optional subtle energy spark accents around the fusion stages. Use thin uniform line weight, flat vector-style shapes, and minimal soft glow.
