Best Answer: Hi! I signed up for the class and I will take it next year. (I'll be a sophomore next year). Bot of my older brothers took it so I know a lot about it. Because the prerequisites for the course are: Chemistry, Biology and Algebra 2 and geometry, the course includes a lot from these. The AP test is hard.
Radon is a chemical element with symbol Rn and atomic number 86. It is a radioactive, colorless, odorless, tasteless noble gas, occurring naturally as a decay product of radium. Its most stable isotope, 222Rn, has a half-life of 3.8 days.Radon is one of the densest substances that remains a gas under normal conditions.adon is produced by the radioactive decay of radium-226, which is found in uranium ores, phosphate rock, shales, igneous and metamorphic rocks such as granite, gneiss, and schist, and to a lesser degree, in common rocks such as limestone.
