In the "chocolate chip cookie dough model" of the atom, the chocolate chips represent negatively charged electrons. The cookie dough would represent the positively charged "soup" in which the electrons (the chocolate chips) are embedded. This analogy reflects the idea that electrons are distributed throughout a positively charged space.

so whats the answer

The answer is negatively charged electrons. In the chocolate chip cookie dough model, the chocolate chips represent the electrons, which are negatively charged, while the dough represents the positively charged matter of the atom.
