During the period of Reconstruction after the Civil War, the South was essentially in ruin. There was lots of political, economic, and social instability.

In the South, some looked for work, some bought up cheap land, and others meddled in politics. However, some had genuine ideals and hoped to help the South. They wanted to reform these states and advocated for the free slaves.

because the two particles have an equal charge, the charges will cancel out and give the atom an overall charge of 0. so, if at atom has 35 protons in the nucleus, we could expect it to have 35 electrons orbiting that nucleus.
