1- sodium and potassium
2- Oxygen as non metal is essential for our life and all living beings inhale it during breathing.
3- Nitrogen is the nonmetal used to enhance the growth of plants.
4- Chlorine, a greenish yellow gas , generally used in the form of tablets is used to dis-infect water.
5- that is IODINE
tincture of iodine is prepared by dissolving iodine in KI solution & then add alcohol or spirit. it was widely used some years ago for treating woods as antiseptic.
6a-
copper-
Copper is easily stretched, molded, and shaped; is resistant to corrosion; and conducts heat and electricity efficiently. As a result, copper was important to early humans and continues to be a material of choice for a variety of domestic, industrial, and high-technology applications today.
b- nitrogen -
The element is used in controlling pollution. It is effective in getting rid of unstable organic compounds in liquids. Many industries use it to destroy toxic liquids and vapors in industrial tools. As nitrogen dioxide, the element is vital in the industrial sector. It also serves as an oxidation reaction catalyst. Apart from being an oxidizing agent, it can also be used as a flour bleaching agent and rocket fuel.
c- carbon
Carbon compounds are important in many facets of the petrotchemicals industry as the feedstock is carbon-based. Carbon is also the basis of fuels such as coal and oil since both coal and oil are rich in carbon. Carbon as graphite is a good lubricant. Carbon is a key component of steel.
d- phosphorus
White phosphorus is used in flares and incendiary devices. Red phosphorus is in the material stuck on the side of matchboxes, used to strike safety matches against to light them. By far the largest use of phosphorus compounds is for fertilisers. Ammonium phosphate is made from phosphate ores.
e- aluminum
Transportation (automobiles, aircraft, trucks, railway cars, marine vessels, bicycles, spacecraft, etc.) as sheet, tube, and castings.
Packaging (cans, foil, frame of etc.).
Food and beverage containers, because of its resistance to corrosion.
f- Sulphur
Sulphur is also used in many other industries including non-ferrous metals, pigments, fibers, hydrofluoric acid, carbon disulphide, pharmaceuticals, agricultural pesticides, personal care products, cosmetics, synthetic rubber vulcanization, water treatment, and steel pickling.
