Common uses of element based on their property

Uses of elements based on the periodic trend-electronegativity, metallic property, atomic radius,.

1. Common uses of element Based on Periodic Trends Based on their Properties

2. Common uses of elements based on the periodic trends Some elements are used according to the trends that they follow and exhibit in the periodic table. As it was associated to the properties they have.

3. Examples: Cesium – has low ionization energy, and is used as photosensors. Used as automatic doors, burglar alarms, and other devices that use photosensors.

4. Examples: Fluorine – has the highest electronegativity, and though it may be very reactive it has many uses in the industry. It is used in toothpaste to help avoid decay of teeth. Also used in ceramics.

5. Examples: Copper – has metallic properties that can contribute to a wide range of uses in the industry. Since it has high electrical conductivity, it is used in most electrical wirings as current flows easily through it.

6. Common uses of elements based on their properties Alkali Metals Have many industrial uses. Most are soluble in water. Alkaline Earth Metals Important commercially. Mg(OH)2- ingredients of antacids. CaO - used in steel industry.

7. Common uses of elements based on their properties Sodium hydroxide – known as the caustic soda, used in making soap, detergents, paper, textiles, and rayon. Sodium benzoate –aka benzoate soda, added to food and drinks as a low cost preservative.

8. Common uses of elements based on their properties Transition Metals Copper, silver and Gold – valuable in high technology because they have high electrical conductivity. Titanium, chromium and zinc – corrosion-resistant which makes them very useful in different industries. Mercury – easily forms alloys called amalgams, with almost all common metals, except iron. Also used in thermometers and barometers.

9. Common uses of elements based on their properties Inner Transition Metals Terbium – used in television screens to produce green lights. Neodymium- used in making lasers. Promethium - used as electric power source for artificial hearts and pacemakers. Uranium and Plutonium- are used as raw materials in the production of nuclear energy.

10. Common uses of elements based on their properties Representative Elements Aluminum- used in construction materials, aircraft parts, and cooking utensils. Boron- brittle black metalloid present in boric acid and borates- used as mild antiseptic and water softener.

11. Common uses of elements based on their properties Representative Elements Tin and Lead – most commonly used metals. Both unreactive to acids, air and water. Nitrogen – used in production of ammonia—colorless gas with irritating odor used in making cleansing products and fertilizers. -has the ability to easily freeze and chill food. -in medicine, it is used to freeze small tumors and other damaged tissues, which consequently die, become very brittle and fall off after some time.

12. Common uses of elements based on their properties Representative Elements Phosphorus - has a tendency to ignite spontaneously. Arsenic- small amount is used to make alloys, transistors, and light emitting diodes (LEDs). These things are used in electronic devices like calculators, clocks and watches.

13. Common uses of elements based on their properties Representative Elements Fluorine - present in nonstick coating of pans. Chlorine- green gas used for disinfecting water. Iodine - used in making certain antiseptic agents.

14. Common uses of elements based on their properties Representative Elements Neon - used in advertising signs. Helium- used to fill balloons and blimps.
