A lack of food and water

In a region with a low crude birthrate, a high crude death rate is most likely indicative of a lack of food and water. This is because without food and water, people can die, thus causing a high crude death rate. Food and water is necessary for survival.

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.

's the question?
