In the periodic table what are the 4 least reactive non metals in the periodic table and their application in the daily life situation?

The 4 least reactive nonmetals in the periodic table are:

1. Helium (He)
2. Neon (Ne)
3. Argon (Ar)
4. Krypton (Kr)

These nonmetals are known for their low reactivity and are often used in various applications in daily life. Some examples include:

1. Helium is commonly used in balloons, airships, and as a coolant in nuclear reactors. It is also used in cryogenics and as a shielding gas in arc welding.

2. Neon is used in neon signs, advertising displays, and in high-voltage indicators. It is also used in vacuum tubes, television tubes, and as a refrigerant.

3. Argon is used in welding and metal fabrication to create an inert atmosphere that prevents oxidation. It is also used in the production of specialty glass and as a shielding gas in gas tungsten arc welding.

4. Krypton is used in lighting applications, such as in high-powered xenon flash lamps and in fluorescent lamps. It is also used in laser technology and in certain types of insulation materials.

Overall, these least reactive nonmetals play important roles in various industries and technologies, contributing to our daily lives in numerous ways.

Four Least Reactive Nonmetals in the Periodic Table:

1. Helium (He): Inert gas with no known applications.
2. Neon (Ne): Inert gas used in lighting, lasers, and cryogenics.
3. Argon (Ar): Inert gas used in welding, food preservation, and incandescent bulbs.
4. Krypton (Kr): Inert gas used in lighting, lasers, and medical imaging.

Applications in Daily Life Situations:

1. Neon:
- Used in advertising signs and street lighting due to its bright red glow.
- Used in laser pointers and surgical lasers for precise cutting.

2. Argon:
- Used in protective welding atmospheres to prevent oxidation of metals.
- Used in food packaging to replace oxygen and extend shelf life.
- Used in incandescent bulbs to fill the glass envelope and prevent filament oxidation.

3. Krypton:
- Used in high-intensity discharge (HID) lamps, providing a bright, white light.
- Used in medical imaging, such as computed tomography (CT) scans, to enhance image contrast.
- Used in some lasers, such as krypton-fluoride (KrF) lasers, for microfabrication and medical procedures.

4. Helium:
- Used in party balloons and airships due to its lightweight and non-flammable nature.
- Used in cryogenics for cooling scientific equipment and preserving biological samples.
- Used in medical applications, such as MRI scans and breathing mixtures for scuba diving.
