Question

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 thomsons beams? an atoms negative particles are surrounded by positive matter, so the positive particles are easier to remove. an atoms positive particles are surrounded by negative matter, so the negative particles are easier to remove. an atoms smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to remove. an atoms larger positive particles are at a distance from the central negative particles, so the positive particles are easier to remove.

Explanation:

In an atom, electrons (negative - charged particles) are smaller and located outside the nucleus (where positive - charged protons are). They are at a distance from the central positive particles and are easier to remove, which is consistent with the charged particles in Thomson's beams being electrons.

Answer:

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