Write a chemical equation for the reduction step in hte formation of silver nanoparticles

For the formation of any metal nano-particles, a reduction reaction takes place. In this reaction, the metal ion reacts with a reducing agent to form a metal nano-particle.
Similarly, for the formation silver nano-particles, the silver ions must get reduced to elemental silver.
Ag+ (aq) + e- >  Ag0 (s)

The correct answer should be "electrons orbit the nucleus in circular motions exactly as shown on the classic bohr model."
