Atomic number 12 belongs to magnesium, which occurs naturally in chlorophyll as sunlight is converted into sugars by plants. It is a whitish metal, stable in the air, but reactive to boiling water. Once used as a component of photography and theater lighting, it is now used in alloys to provide strength to objects without adding mass. Compounds of magnesium are used to make household products such as dyes, medicine, cement and in the manufacturing processes of cotton products.
Carbon
Carbon is atomic number 6, and has two common crystalline forms. One form produces diamonds, the hardest substance known. This happens when the atoms are symmetrically arranged. They very rarely react with chemicals. The second form, graphite, is often used in lead pencils. It is a soft, conductive substance that is formed when the atoms are layered. There is also a non-crystalline form of carbon in charcoal, and carbon and iron alloys produce steel.
Nickel
Atomic number 28 indicates nickel, a lustrous silver metal with a slight golden hue. The element is rumored to be named for a mythological creature, who medieval German copper miners blamed for a lack of copper ore in their extractions. Nickel is strong and thus is used in household products such as:
cookware
cutlery
sinks
flatware
cooking utensils
faucets
Many kinds of jewelry are made from nickel-silver, a nickel-copper-zinc alloy.
Sodium
The metallic element sodium is atomic number 11, and it is essential for human and animal life. The lustrous silver metal is a component of electrolytes, and makes possible the transmission of nerve impulses in the body. Sodium is readily found in common table salt, and is used in oral rehydration drinks and baking soda. It is also the substance found in most fire extinguishers. Sodium compounds are used in soap, paper and glass manufacturing.
Silver
Atomic number 47 is silver, a metallic element that has been used for thousands of years. Silver mines produce the white metal, which in its purest form is soft and pliable. Common household products containing silver are mirrors, jewelry, coins and flatware, and it is used as a conductor in electrical work. It is also found in some antibacterial products and antibiotic medicines, as well as silver-cadmium batteries.
Silicon Carbide
Silicon carbide occurs naturally, although rarely, with the molecular formula SiC. One molecule of silicon carbide is one silicon atom and one carbon atom. When grains of silicon carbide are manufactured and fused together, they form an extremely hard, durable substance that is used in specialized items like car brakes, turbine mechanics, and certain types of seals and bearings. Large crystals of silicon carbide can be grown artificially, often as the diamond imitation jewel moissanite.
Tungsten Carbide
Tungsten carbide is a fine, grey powder. Molecularly, it contains equal parts tungsten and carbon. When pressed, it forms an extremely hard substance with many applications. It's used in the military in armor-piercing weaponry and found on the tips of poles used by hikers. Tools, the balls of ball point pens, razor blades and jewelry are some other items sometimes made with tungsten carbide. Tungsten carbide wedding rings for men are popular due to their dark luster and high resistance to scratching.
Boron Carbide
Boron carbide is a ceramic material and one of the hardest synthetic substances known. Its chemical makeup includes four boron atoms and one carbon atom. It's used in tank armor, security padlocks and cutting tools, among other specialized applications. With a high resistance to wear, a specialized application of boron carbide includes the nozzles of sandblasters. Due to its chemical reactions with atom parts known as neutrons, it also has a use in nuclear reactors.
Aluminum Carbide
Aluminum carbide is in small parts a byproduct of manufacturing calcium carbide. It looks like yellow or brown crystals and dissolves in water. Typically, it's used in cutting tools or it is added to some metals to prevent the misshaping that sometimes happens to when pressurized over time.
Uses of Carbide
The word "carbide" denotes a compound of carbon and another element or elements. When the term is used by itself, it usually refers to calcium carbide, or sometimes, tungsten carbide. Other types of carbide include silicon carbide, boron carbide and aluminum carbide. These substances have various industrial, engineering and household uses.
