J. J. suggests the that an atom subjected to a high voltage becomes charged because it's made of some positive material with small bits of negative material embedded in it, like raisins in a pudding. The high voltage rips the negative bits out, leaving the positive material behind, and making the once neutral atom charged.

True

Explanation:

Thomson proposed that:

- An atom consists of a positively charged sphere and the electrons are embedded in it. Thus, the atom is visualised as pudding or cake of positive charges with raisins (electrons) embedded into it. Hence it is raisin pudding model or watermelon model.

- The negative and positive charges are equal in magnitude. So that atom as a whole is electrically neutral.

- The force on the electron is developed by the potential difference applied across i. e how cathode ray produces a beam of electron.
