The charged particles in the beams that Thomson studied came from atoms. As these particles moved away from their original atoms, they formed a visible beam. The current model of the atom includes protons, neutrons, and electrons.

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.

Katherine Howard · Answer 1

An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to remove.

Explanation:

An atomic model with negative charges located at a distance from central positive particles means that the negative charges are more exposed, on the outside of the atom, and, therefore, are more susceptible to being separated from the atom, while the positive particles that are inside the atom are more protected.

Thus, since the charged particles in the beams that Thomson studied moved away from their original atoms, you can imagine that those particles were, indeed, at a distance from the central positive particles, so they are easier to remove.
