Environmental Protection Agency monitors 80 different causes that may affect drinking water. Microbial contaminants include bacteria and viruses. Most people with compromised immune systems can get dangerously ill. Contaminants like solvents‚ pesticides‚ radium and arsenic are more sinister.

Although Joseph John (J.J.) Thomson (1856 - 1940) was mainly a physicist‚ his discoveries are closely connected to the chemical community. Thomson used Crookes high vacuum cathode ray tube in his discovery of electrons. He found the green beam produced by the cathode ray tube was a completely negatively charged material. Experimenting with different electrically charged plates and magnets in the cathode ray tube and observing the deflection of the rays he had enough evidence to say that particles

Bacteria that feed on decaying organic matter like plants or animals produce methane and carbon dioxide‚ which are released into the atmosphere. Earth’s crust is composed is composed of a radioactive element called Uranium. Uranium turns into Radium once it decays afterward forming Radon. Radon is a gas that combines with air through evaporation. Human activities or anthropogenic sources also cause air pollution. These activities mostly involve burning of fuel. Stationary sources

Within a cast‚ there were subgroups. Those groups were usually composed of people in the same year and people who had the same attitude regarding the play we were in.

This was I suppose‚ partly due to the fact that they were disrespected by a senior castmate who complained about them behind their backs frequently. These subgroups directly contribute

Table of the Elements - listing them by their atomic weight and grouping them with similar characteristics. * 1897: JJ Thomson discovered electron and isotopes‚ and invented the mass spectrometer. * 1898: Marie Curie discovered and isolated radium‚ a new element which unprompted disintegrated into other elements. This proved that the atoms of one element at least were not indivisible. * 1911: Ernest Rutherford established that the nucleus was very dense‚ very small and positively charged

Alkaline Earth Metals are all found in the Earth’s crust‚ but not in the elemental form as they are so reactive. Instead‚ they are widely distributed in rock structures. The Alkaline Earth Metals are: Beryllium Magnesium Calcium Strontium Barium Radium Elements classified as Transition Metals The elements classified as "Transition Metals" are located in Groups 3 - 12 of the Periodic Table. Elements classified as Transition Metals are ductile‚ malleable‚ and conduct electricity and heat. The
