Sodium is an element on the periodic table with the chemical symbol as Na. Sodium, discovered by the English Chemist Sir Humphry Davy, is in the Alkali Metals group on the Periodic Table and it is a soft, silver/white color. Sodium, which is found in the Earth's crust, is important to society.
Sodium originated from the Arabic word “suda” meaning headache because sodium carbonate was used as a headache remedy. It is also one of the most well-known compounds to ancient people (Newton). It is a component of sodium chloride (NaCl) which is found everywhere in nature (Sodium Lenntech). Sodium is the sixth most abundant element in the Earth’s crust and the second most abundant element dissolved in sea water (Sodium Lenntech). Although sodium is abundant on Earth, it is never found in free nature (The Element). Our bodies need sodium in order to work properly. The body needs sodium to help control the muscles and nerves (Sodium in). The body also uses sodium to control volume and blood pressure. Sodium is a slivery-white metal that always occurs as part of a compound (Newton). It is very easy to cut and when it is cut it changes to a very dull color because it is exposed to oxygen (Sodium Lenntech). Sodium must be stored in a moisture free environment because it is very highly reactive (Element). It has a chemical symbol of Na, and has an atomic mass of 22.99 and a periodic number of three (Bentor). It was founded hundreds of years ago.
Sodium was founded in 1807 by an English Chemist named Sir Humphrey Davy (Bentor). It was found through the electrolysis of caustic soda (The Element). This means that he found a way to extract sodium from compounds (Newton). First Sir Humphrey Davy would extract a number of active elements and then pa...

Ionic compounds are normally a combination of a metal, along with one or more non-metals. If you recognize the two ions, you have the name of the compound. For example, the familiar calcium ion, Ca2+ must combine with two iodides, I–, to afford calcium iodide, CaI2. For ionic compounds this means that the formula unit must have an equal number of positive and negative charges because ionic
Molybdenum use increased a lot during World War I, when demand for tungsten made tungsten rare, and strong steels were at expensive. Molybdenum is used in aircraft and missile parts, and in filaments. Molybdenum acts as a catalyst in the petroleum industry for removing organic sulfurs from petroleum products.
Many elements, like lead, are very important to the structure and formation of many of the products we use. Throughout history, lead has been developed, mined, extracted, and used. Lead, since its finding thousands of years ago, has proven to be a tricky element with many diverse health effects. Scientists have developed products, and processes that still continue to used lead. Lead is an extremely important and influential element in our daily lives.

The origin of the name "nickel" is a derivative from the German word "kupfernickel", meaning "Devil's Copper" or "St. Nicholas's Copper".The chemical properties of nickel are as follows: Nickel has the atomic number of twenty-eight. The atomic symbol of nickel, "Ni". It has the atomic weight (mass) of 58.70, to be exact, 58.693. It occurs in five stable isotopes. Physically, nickel is a lustrous silvery-white and takes on a hard polish.
The name Neon came from another Greek word as well. That word is “neos”. Neos is translated into new. Neon has the chemical number of 10, the atomic weight of 20, and the chemical symbol of “Ne”. When Sir Ramsay liquified the air, he was able to liquify Neon.
These last two years, however, I started to gain weight and have become concerned with my diet. Changing my poor eating habits has been difficult for me, however, having this assignment has taught me that it is not as difficult as I previously imagined. Nutrition experts in the United States and Canada have a list of standards with four list values. These list values are called the Dietary Reference Intakes. The DRI committee sets these values for vitamins, minerals, calories, and nutrients.
Potassium is a solid silvery white element. It is soft and can be cut with a knife. Potassium is the least dense known metal, besides lithium. It is the seventh most abundant element. It makes up about 1.5% by weight of the earth's crust. It decomposes in water because of the hydrogen. It usually catches fire during reaction with water.
As one of the most easily recognizable elements on the periodic table, Silver is not only one of the worlds first discovered elements, but it is also quite important. It has estimated to have been around since 3000 BC, where it was first mined in what is now known as Turkey. Silver, whose name was derived from the AngloSaxon word seolfor, has an atomic mass of about 107.9, its symbol is Ag (derived from the Latin word for silver, argentum), and it is the best conductor out of all the metals on the periodic table. It has quite the production history, too. When silver was first discovered in Anatolia (modernday Turkey), it was a valuable resource for the nearby civilizations.

Electrical conductivity refers to a substances ability to carry moving electrons (conduct electricity). In order to do so, there must be a supply of delocalised electrons. While in a solid state, ionic substances can not conduct electricity as there are no delocalised electrons or free/mobile ions to act as charge carriers. In an aqueous ionic solution, the H2O molecules break apart the crystal lattice structure of the ionic substance into individual ions, surrounding each ion in a jacket of hydration. Below is the equation that describes the dissociation of NaCl when in H2O solvent.
From the Greek word "lithos" meaning "stone", it was so named due to the fact that it was discovered from a mineral source; whereas the other two common Group 1 elements, Sodium and Potassium, were found in plant sources. Its symbol, Li, was taken directly from its name. Soon after stumbling upon Lithium, Arfvedson also found traces of the metal in the minerals Spodumene and Lepidolite. In 1818, C.G. Gmelin discovered that Lithium salts color flames a bright red. Neither, Gmelin or Arfvedson, however, were able to isolate the element itself from the Lithium salts. They both tried to reduce the oxide by heating it with Iron or Carbon, but neither met with the success of W.T. Brande and Sir Humphrey Davy. They managed to perform the first isolation of elemental Lithium by the electrolysis of Lithium oxide. Electrolysis is a chemical reaction, which is brought about by the passage of current from an external energy source such as a battery. In 1855, the scientists Bunsen and Mattiessen isolated larger quantities of the metal by electrolysis of Lithium chloride.
