Thomson's model of an atom: (i) An Atom Consist of a positively charged sphere and the electrons are embedded (ii) The negative and positive charges are equal in magnitude, so, the atom as a whole is electricity neutral

✅ Correct.

Your description of Thomson's atomic model is accurate. It correctly states that the atom is a positively charged sphere with embedded electrons, and that the equal magnitude of positive and negative charges makes the atom electrically neutral.
