The following is an excerpt from a speech President Obama made in 2011, when describing the economic collapse of 2008: "But for most Americans, the basic bargain that made this country great has eroded.

Those at the very top grew wealthier from their incomes and their investments - wealthier than ever before. But everybody else struggled with costs that were growing and paychecks that weren't- and too many families found themselves racking up more and more debt just to keep up.....

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.
