given the name silicium‚ with an -ium word-ending to suggest a metal‚ a name which the element retains in several non-English languages. However‚ its final English name‚ first suggested in 1817‚ reflects the more physically similar elements carbon and boron. Percentage Silicon is the eighth most common element in the universe by mass‚ but very rarely occurs as the pure free element in nature. It is most widely distributed in dusts‚ sands‚ planetoids‚ and planets as various forms of silicon dioxide

quercetin found in apples protects brain cells against neuron-degenerative disorders like Alzheimer’s disease. An apple a day may not keep any physicians at bay‚ but apples are very nutritious. They are high in fiber‚ important for digestive health‚ and boron‚ which promotes bone growth. Apples are also rich sources of photochemical‚ an anti-oxidant found in plants‚ fruits and vegetables. A raw apple‚ weighing 138 g with skin‚ provides 6.3 mg of vitamin C‚ or ascorbic acid. One apple provides roughly 10

How does Nuclear power work and what happened at Chernobyl? What would you do if your town had a nuclear power plant explosion? Would you help clean up or would you just leave town? I would help the people of my town by cleaning up. The chernobyl explosion was caused by an operator error‚ and cost a lot of money and hurt a lot of people. Nuclear power is made up of atoms that are constructed like a mini solar system. By the late 1950’s nuclear power was developed. There are two types of uranium

The other‚ more common macronutrients are called secondary nutrients‚ as they are not of as much importance. Micronutrients‚ the other classification‚ consist of all the other elements and compounds required for sufficient growth‚ such as iron‚ boron‚ manganese‚ copper‚ zinc‚ molybdenum and chlorine. In some cases‚ these nutrients are found to be missing in soils‚ but it is extremely uncommon. As plants need to retrieve all of their nutrients from the soil‚ many methods have been developed in

The development of Periodic Table Elements such as gold and silver have been known since the earliest times. In 1649‚ a German alchemist‚ Hennig Brand made the first scientific discovery of an element‚ phosphorous. In the next 200 years‚ knowledge about the properties of elements and their compounds was gained. By 1869‚ 63 elements had been discovered in total. Scientists began to categorise those elements according to the similarities of their physical and chemical properties‚ which become the

Nanotube is a nano dimensional made by using carbon. It has many unique properties. HOW IS IT POSSIBLE? Pure Diamond structural carbon is non-conducting in nature. In order to make it conducting we have to perform doping process. We are using Boron as the p-type doping Agent and the Nitrogen as the n-type doping agent. The doping process is similar to that in the case of Silicon chip manufacturing. But this process
