Element Properties: 9-15 atomic number

MIRAMAR, Fla. - May 26, 2021 - PRLog -- FLUORINE
Fluorine is the most active member of the halogen family, and produces the most stable compounds. It occurs as either the mineral fluorine, or the mineral cryolite. Freon, the refrigerant, contains fluorine. Cryolite, or sodium aluminum fluoride, is an important flux in the electrolytic production of aluminum metal. Fluorine is found in tap water and toothpaste, which had beneficial effects on teeth. Other fluorine compounds are used as insecticides and wood preservatives.

NEON
Neon is obtained from the fractional distillation of liquid air. Its main use is in neon signs. Neon signs are made of helium, neon, argon, or mercury at different pressures. These are then put into different colored glass, which gives off different colors.

SODIUM
Sodium is a light silvery-white metal, lustrous when freshly cut, but tarnishes when exposed to air, becoming dull and gray. It is too active to be found in nature, and reacts vigorously with water, exploding upon contact with a large chunk. Other uses are the manufacture of a variety of organic chemicals, and the reduction of titanium metal. It is also a good electron source for photoelectric cells and cyclotrons.

MAGNESIUM (https://www.edge-techind.com/category/Magnesium-Mg-130-1....)
Magnesium is one of the most common elements in the earth's crust. It burns with a brilliant white color, and slowly oxidizes in moist air. It is an important structural metal, often used in either pure or alloyed form with aluminum in the construction of aircraft. It is also frequently used in the production of objects requiring a light weight. Powdered magnesium is sometimes used in place of aluminum in the thermite reaction.

ALUMINUM
Aluminum is a white, malleable, ductile metal, with a somewhat bluish tint. It occurs in a variety of silicate rocks, mainly mica and feldspar. Aluminum also occurs as cryolite. Because of its light weight, resistance to corrosion, and tensile strength, it is excellent for the construction of the structure of a building. Because it can easily be rolled into sheets, much is used for aluminum foil. Aluminum powder is sometimes used in some types of paint.

SILICON (https://www.edge-techind.com/category/Silicon-powder-100-...)
Silicon is black-gray and a poor conductor of electricity. It is never found free always combined with oxygen. The two principal combinations of silicon are silicon dioxide, which is found as flint, quartz, sand, sandstone, agate and amethyst and silicate rocks. These rocks range from garnet to asbestos.

PHOSPHORUS
Phosphorus exists in three main allotropic forms—white, black, and red. It is too active to be found in nature, and most of it is combined with oxygen. Its principal ores are phosphorite and apatite. White phosphorous is waxy, soft and translucent, and becomes brittle at 5.5°C. It is crystalline, insoluble in water, and extremely poisonous.
