Environmental problems associated with geothermal energy include: a. water and noise pollution and devastation of caribou herds. b. air pollution, corrosion of pipes, and may be toxic to fish. c. killing of birds, noise pollution, and is very expensive. d. being non-renewable, smells, and has large volumes of waste water.

b. air pollution, corrosion of pipes, and may be toxic to fish

Explanation:

Use of earth heat to generate electrical energy through geothermal power plants is known as geothermal energy. There are certain disadvantages associated with geothermal power generation. One such problems is air pollution.  Steam from the Earth brings up heavy metals such as Sulfer, Radon Salts and toxic gases which pollute environment. In the process of energy production, hazardous sludge produced which contaminate soil and water. Due to presence of heavy metals it corrodes pipes. Geothermal plants should be constructed with utmost care otherwise it greatly impact on local environment.

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.
