![]() It is also used in the street lights that are orange, and ultra violet. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. ![]() Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. It is used in the preparation of organic compounds. Sodium is a chemical element with atomic number 11 which means there are 11 protons in its nucleus. It is named after soda, a name for sodium hydroxide or sodium carbonate. There are 20 known isotopes of sodium but only one 23Na is. He made it by the electrolysis of sodium hydroxide. Due to this, sodium is a highly reactive chemical element and is found only in the form of compounds. Some of the most common are: table salt (NaCl), soda ash (Na 2CO 3), baking soda (NaHCO 3), caustic soda (NaOH), Chile saltpeter (NaNO 3) and borax (Na 2B 4O 7♱0H 2O).Įstimated Crustal Abundance: 2.36×10 4 milligrams per kilogramĮstimated Oceanic Abundance: 1. Sodium was discovered by Sir Humphrey Davy, an English scientist, back in 1807. Sodium vapor is used in streetlights and produces a brilliant yellow light. Liquid sodium has been used as a coolant for nuclear reactors. Sodium is used in the production of titanium, sodamide, sodium cyanide, sodium peroxide, and sodium hydride. dude why dont you tell about the exact date when they discovered uses it was dicovered by sir humphrey davy in england in 1807. Since sodium can ignite on contact with water, it must be stored in a moisture free environment. In 1807 Sir Humphry Davy became the first to prepare sodium in its elemental form, applying electrolysis to fused sodium hydroxide (NaOH). According to the Jefferson National Linear Accelerator Laboratory, the properties of sodium are: Atomic number (number of protons in the nucleus): 11. Pure sodium was first isolated by Sir Humphry Davy in 1807 through the electrolysis of caustic soda (NaOH). Since sodium can ignite on contact with water, it. Although sodium is the sixth most abundant element on earth and comprises about 2.6% of the earth's crust, it is a very reactive element and is never found free in nature. Pure sodium was first isolated by Sir Humphry Davy in 1807 through the electrolysis of caustic soda (NaOH).
