What is radon House?
Radon is a radioactive gas that has been found in homes all over the United States. It comes from the natural breakdown of uranium in soil, rock, and water and gets into the air you breathe. Radon typically moves up through the ground to the air above and into your home through cracks and other holes in the foundation.
What does atomic number 54 mean?
Xenon has atomic number 54; that is, its nucleus contains 54 protons.At standard temperature and pressure, pure xenon gas has a density of 5.894 kg/m 3, about 4.5 times the density of the Earth’s atmosphere at sea level, 1.217 kg/m 3. As a liquid, xenon has a density of up to 3.100 g/mL, with the density maximum occurring at the triple point. Liquid xenon has a high polarizability due to its
