What is the best use of an atomic model to explain the charge of the particles in thomson’s beams? an atom’s negative particles are surrounded by positive matter, so the positive particles are easier to remove. an atom’s positive particles are surrounded by negative matter, so the negative particles are easier to remove. an atom’s smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to remove. an atom’s larger positive particles are at a distance from the central negative particles, so the positive particles are easier to remove.
