Explain why argon, krypton or xenon are used in these lamps. The hot metal wires will burn away if any oxygen from air is present in the lamp. Argon, krypton and xenon are very unreactive.

They replace the air inside the lamp, preventing the metal wire from burning away. Chemical properties of the noble gases Compared to other elements , the noble gases are inert - they are extremely unreactive. Explaining the inertness of noble gases When elements react, their atoms complete their outer shells by losing, gaining, or sharing electrons. Excimer lasers have many industrial, medical, and scientific applications. They are used for microlithography and microfabrication, which are essential for integrated circuit manufacturing; and for laser surgery, including laser angioplasty and eye surgery.

Key Points Noble gases are colorless, odorless, tasteless, and nonflammable gases under standard conditions. In the periodic table, the noble gases are arranged according to their boiling point. Noble gases are widely used in different fields, from incandescent lighting to excimer lasers.
