$\mathfrak \red{\large \: Answer:-}$

According to Thomson€™s model of the atom, an atom consists of both negatively and positively charged particles. ... The negatively charged particles are embedded in the positively charged sphere. These negative and positive charges are equal in magnitude.

Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or loses one or more electrons, it becomes an ion.

Thomson knew that atoms had an overall neutral charge. Therefore, he reasoned that there must be a source of positive charge within the atom to counterbalance the negative charge on the electrons. ... The plum pudding model depicts the electrons as negatively-charged particles embedded in a sea of positive charge.
