WebRutherford explained the nucleus of an atom and Bohr modified that model into electrons and their energy levels. Bohr’s model consists of a small nucleus (positively charged) surrounded by negative electrons moving around the nucleus in orbits. Bohr found that an electron located away from the nucleus has more energy, and the electron which ... WebChristian Bohr, who was credited with the discovery of the effect in 1904. The Bohr effect is a phenomenon first described in 1904 by the Danish physiologist Christian Bohr.
