The jujube cake model was put forward by Thomson. Raisin cake, also known as jujube cake model and raisin bread, is an atomic structure model proposed by scientist Thomson.

Electrons with negative charges are dispersed in atoms, and these electrons are distributed in symmetrical positions. When these electrons are at rest in an equilibrium position, they will vibrate and make the atoms glow. Thomson's atomic model was widely recognized for a period of time in history, and was later replaced by Rutherford's nucleated model.
