Humphry Davy

Scientists make important contributions to technology and medicine through their discoveries. Nikola Tesla is distinguished for his futuristic inventions which serve as components of electrical systems in modern times. Another scientist who influenced contemporary technology is Joseph Henry, who developed the telegraph. Likewise, the acclaimed scientist Hans Christian Ørsted discovered electromagnetism, which broadened the range of scientific possibilities. Despite the eminence of Tesla, Henry,…

Big business, economic growth and international involvement turned America into an industrial giant in the late 19th century because the railroads was one of the biggest change that happened to america. One , it made transportation easier for travelers and second, it made getting goods though place to place faster. A second thing that happened to america that changed many things in america was the way that rockefeller made the pipes for the olis all around europe and got the oil all around…

atomic number to my element is 11, the mass number is 23, the number of neutrons is 12, the protons are 11 and the electrons are also 11, the electron configuration of my element is 1s22s22p63s1. The person who discovered my element is Humphry Davy. He discovered sodium in 1807. Origin of sodium is derived from the English word ‘soda’. The appearance of sodium is soft metal that tarnishes within seconds of being exposed to the air. It also reacts vigorously with water. Used as a heat…

people are taught that everything from the idea to the finished product was the property of Edison. The truth of the matter is, Thomas Edison did not create the light bulb. Many overlook the man who truly produced the first light bulb, Sir Humphry Davy. Sir Humphry Davy was an English chemist who was responsible for illuminating an arc lamp by transferring electricity through a platinum wire in 1802…

CALCIUM Calcium is a mineral found in many foods. The body needs calcium to maintain strong bones and to carry out many important functions. Not having enough calcium can cause many health problems. Calcium insufficiency also causes weak bones and tooth decay. This is because almost all calcium is stored in bones and teeth. This program will help you better understand the importance of calcium in the body and how you can make sure you are getting the right amount. Calcium is the chemical…

The 19th century was one of the greatest times of change and innovation in history. Inventions that changed the world sprung up left and right. Almost all significant inventions of this time period are still around today. One of the greatest weapons of war in its time was the ironclad. Ironclads were steam powered warships protected by iron or steel plating. they were first used successfully in the mid 19th century. ironclads were designed for several roles such as: dominating sea battles,…

Periodic Table of the Elements My elephant drawing represents potassium. I drew a banana because they are high in potassium. I also drew water (h2o) which is very violent when it hits potassium (k). The elephant itself represents element potassium. The red color of the elephant symbolizes it being burnt from the water. When water hits potassium it creates a massive explosion resulting in the elephant being wounded. The elephant undergoes a lot of corrosive reactions. The ionization decreases…

Calcium can be considered as one of the most used elements of the periodic table. People tend to use, eat or drink it every day even if they do not know it. The symbol for calcium is very simple: Ca. Its atomic number is 20.(Helmenstine, 2015) Calcium has 20 electrons and 20 protons because electrons and protons will always have the same amount. There are also 20 neutrons in calcium due to the subtracting of the atomic weight and the number of protons to get the number of neutrons.(Nelson,…

invented so you do not have to feel pain while in surgery? In 1772, English scientist Joseph Priestley discovered the gas nitrous oxide. Many people thought this gas was lethal, even in small doses. However, in 1799, British chemist and inventor Humphry Davy decided to find out by experimenting on himself. Surprisingly, he found that nitrous oxide…

But there were many other inventions that led up to this one, such as Humphry Davy inventing the first electric light in 1802. And Warren de La Rue who enclosed a coiled platinum filament in a vacuum tube and passed an electric current through it in 1840. In 1850, Joseph Wilson Swan created a light bulb by enclosing carbonized…
