The plum pudding model of the atom, proposed by J.J. Thomson in the early 20th century, states that:

**An atom is made up of electrons in a sea of positive charge.**

In this model, electrons are embedded within a positively charged "soup," balancing the overall charge of the atom. It was a significant early conception of atomic structure before the discovery of the nucleus and the development of the Rutherford model.
