How much money does hydroelectricity cost per kilowatt hours? I pay .07 cents a kWh. If one kilowatt hour of electricity cost nine cents how much does it cost to run a 500 watt light bulb for twenty four hours? 500 watts x 24 hours = 12,000 watt hours or 12kW h. 12 kW h x 9 cents/kW h is $1.08.

Polonium was discovered in 1898 by Polish-French physicist Marie Curie (1867-1934) and her husband, Pierre (1859-1906). They were looking for the source of radioactivity in a naturally occurring ore called pitchblende. Radioactivity is the process by which materials give off energy and change into new materials. Polonium is the heaviest element in the chalcogen family. It is in Group 16 (VIA) on the periodic table. The periodic table is a chart that shows how chemical elements are related to one another. The other chalcogen elements are oxygen, sulfur, selenium, and tellurium.
