Solar Cells Solar Cells Solar cells today are mostly made of silicon, one of the most common elements on Earth. The crystalline silicon solar cell was one of the first types to be developed and it is still the most common type in use today. They do not pollute the atmosphere and they leave behind no harmful waste products. Photovoltaic cells work effectively even in cloudy weather and unlike solar heaters, are more efficient at low temperatures. They do their job silently and there are no movin

Oxygen
Oxygen Oxygen Oxygen and its compounds play a key role in many of the important processes of life and industry. Oxygen in the biosphere is essential in the processes of respiration and metabolism, the means by which animals derive the energy needed to sustain life. Furthermore, oxygen is the most abundant element at the surface of the Earth. In combined form it is found in ores, earths, rocks, and gemstones, as well as in all living organisms. Oxygen is a gaseous chemical element in Group VA of

The Element: Chlorine
The Element: Chlorine The Element: Chlorine General Information We researched the chemical element known as chlorine. Chlorine has an atomic number of 17 and an atomic weight of 35.453. It has a valence number of 3. The element has 3 energy levels. Chlorine exists as a greenish-yellow gas at normal temperatures and pressures. Chlorine is second in reactivity only to fluorine among the halogen elements. Chlorine is a nonmetal. It is estimated that 0.045% of the earth\'s crust and 1.9% of sea wate

KRYPTON
KRYPTON Word Count: 493 I am the chemical element known as Krypton. I can also be referred as Kr. I will be telling you about my history, my properties, my family and my occurrence. I will also be telling you about my uses and ores, also the analytical methods based on me. I received the name krypton from the Greek word hidden because I was hiding for so long, undetected. I am from a rare group of gases called noble gases. The other noble gases are helium, xenon, neon, argon and radon. I was di
