Bohr modelatomelectron- Bohr model (Wikipedia)
In atomic physics, the Bohr model or Rutherford–Bohr model is an obsolete model of the atom, presented by Niels Bohr and Ernest Rutherford in 1913. It consists of a small, dense nucleus surrounded by orbiting electrons. It is analogous to the structure of the Solar System, but with attraction provided by electrostatic force rather than gravity, and with the electron energies quantized (assuming only discrete values).

Perhaps the most enduring of all Greek myths is the story of Perseus and Andromeda, the original version of George and the dragon. Its heroine is beautiful princess Andromeda (Ἀνδρομέδα in Greek). She was the daughter of the weak King Cepheus of Ethiopia and the vain Queen Cassiopeia, whose boastfulness knew no bounds.
