Hydrogen atom first excited state

Bohr-style textbook schematic of a hydrogen atom in its first excited state, with a tiny central proton nucleus and a single electron positioned on the second circular orbit labeled n=2. The electron is shown farther from the nucleus than in the ground state, emphasizing the larger orbital radius. The orbit is a clean circular ring; the first shell may be faintly indicated or omitted, though some versions may show possible orbit rings for context. Use a simple educational diagram style, with the nucleus optionally red and the electron optionally a blue dot. Use thin clean lines, flat colors, and minimal textbook-style detail.
