Bohr model of sodium (Na)

An example figure from the Bohr Model generator.

Bohr model of a sodium atom: a nucleus of 11 protons and 12 neutrons, with 2, 8 and 1 electrons on three shells — A Bohr model of a neutral sodium atom. The nucleus is drawn as 11 red protons and 12 gray neutrons, and 11 blue electrons sit on three rings: 2 on the first shell, 8 on the second and 1 on the third. The single outer electron is sodium’s one valence electron.
