Explanation:

Which of the following statements best describes the changes in American cities from 1900 to 2000? During the early 1900s, the populations of US cities located on the West Coast were the highest, but by 2000, the populations of cities located in the Midwest became greater than those of the East Coast.

The United States population more than tripled from  76 million people in 1900 to 281 million people in  2000,In 1900, the majority (62 percent) of the U.S. population  lived in either the Northeast or the Midwest. However,  by the end of the century, the majority (58 percent) of  the population resided in either the South or West, population density of the Northeast far exceeded  the densities of the other regions from 1900 to 2000.The Northeast  was the most densely populated region and had the  highest percentage of its population living in metropolitan areas throughout the century.

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.
