Approach Solution -2
The chemical element Argon is a noble gas with 18 as its atomic number. It is chemically inert. Argon is the third most abundant gas in the earth’s atmosphere. It is the cheapest alternative gas and therefore can be used as filler. Argon also has low thermal conductivity.
Uses of Argon
Argon is used as:
- Argon is used in fluorescent lighting, high-intensity discharge (HID) lighting, and neon signs.
- Argon is used as a shielding gas in welding processes to protect the weld from oxidation and other forms of contamination.
- It is used as a blanket in a variety of industrial processes to protect the materials from oxidation and contamination.
- It is used in the packaging of certain food items to extend their shelf life and prevent spoilage.
- Argon is used in medical equipment, such as oxygen concentrators, to help deliver pure oxygen to patients.
- It is used in scientific research as a reference material and as a tracer gas.
- Argon is used in some fire suppression systems as a clean, non-toxic alternative to traditional fire-extinguishing agents.
Argon is used in high-temperature welding as an inert shielding gas. It is because even at very high temperatures, argon remains inactive. It generates a non-oxidizing atmosphere and is hence favourable for many industrial processes.
The answer is option (A): "Argon is used in high-temperature welding"

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
