Chemical properties – Chlorine symbol, electronic configuration, density
|
|
|
| Chlorine is a halogen, found in the periodic table in group 17. As the chloride ion, which is part of common salt and other compounds, it is abundant in nature and necessary to most forms of life, including humans. In its elemental form under standard conditions, chlorine is a powerful oxidant and is used in bleaching and disinfectants, as well as an essential reagent in the chemical industry. As a common disinfectant, chlorine compounds are used in swimming pools to keep them clean and sanitary. It is also used in making plastics, solvents for dry cleaning and metal degreasing, textiles, agrochemicals and pharmaceuticals, insecticides, dyestuffs, household cleaning products, etc. | |

Chemical properties – Sulfur symbol, electronic configuration, density
Sulfur
Description: |
|
| Sulfur is an abundant, multivalent non-metal. It is an essential element for all life, and is widely used in biochemical processes. In metabolic reactions, sulfur compounds serve as both fuels and respiratory materials for simple organisms. It is an important part of many enzymes and also in antioxidant molecules like glutathione and thioredoxin. Organically bonded sulfur is a component of all proteins, as the amino acids cysteine and methionine. Disulfide bonds are largely responsible for the mechanical strength and insolubility of the protein keratin, found in outer skin, hair, and feathers, and the element contributes to their pungent odor when burned. The element’s commercial uses are primarily in fertilizers, because of the relatively high requirement of plants for it, and in the manufacture of sulfuric acid, a primary industrial chemical. Other well-known uses for the element are in matches, insecticides and fungicides. | |

Chemical properties – Phosphorus symbol, electronic configuration, density
Phosphorus
Description: |
|
|
Phosphorus is a multivalent nonmetal of the nitrogen group. It is a component of DNA, RNA, ATP, and also the phospholipids that form all cell membranes. It is thus an essential element for all living cells, and organisms tend to accumulate and concentrate it. Today, the most important commercial use of phosphorus-based chemicals is the production of fertilizers, to replace the phosphorus that plants remove from the soil. It is widely used to make organophosphorus compounds. It is also an important component in steel production, in the making of phosphor bronze, and in many other related products. Phosphates are utilized in the making of special glasses that are used for sodium lamps. |

Chemical properties – silicon symbol, electronic configuration, density
Silicon
Description: |
|
| Silicon is the most common metalloid. It has many industrial uses. It is the principal component of most semiconductor devices, most importantly integrated circuits or microchips. It is widely used in semiconductors because it remains a semiconductor at higher temperatures than the semiconductor germanium and because its native oxide is easily grown in a furnace and forms a good semiconductor/dielectric interface. In the form of silica and silicates, silicon forms useful glasses, cements, and ceramics. It is also a constituent of silicones, a class-name for various synthetic plastic substances made of silicon, oxygen, carbon and hydrogen, often confused with silicon itself. Silicon is an essential element in biology, although only tiny traces of it appear to be required by animals. It is much more important to the metabolism of plants, particularly many grasses, and silicic acid forms the basis of the striking array of protective shells of the microscopic diatoms. | |

Chemical properties – aluminium symbol, electronic configuration, density
Aluminium
Description: |
|
| Aluminium is the most abundant metal in the Earth’s crust, and the third most abundant element, after oxygen and silicon. It is the most widely used non-ferrous metal. Aluminium is remarkable for the metal’s low density and for its ability to resist corrosion due to the phenomenon of passivation. Structural components made from aluminium and its alloys are vital to the aerospace industry and are important in other areas of transportation and structural materials. The most useful compounds of aluminium, at least on a weight basis, are the oxides and sulfates. | |
