Which of the following is an inert gas?
Neon
Nitrogen
Oxygen
Hydrogen
Neon
Neon is an inert gas belonging to Group 18 of the periodic table, characterized by having a stable, fully filled valence electron shell. Because its outermost energy level contains an octet of electrons, it is chemically unreactive under standard conditions.

Think of an inert gas as a person who has already finished their dinner and is completely satisfied; they have no desire to 'trade' or 'share' food with anyone else at the table.
He Never Ate Kittens, X-raying Radium (Helium, Neon, Argon, Krypton, Xenon, Radon).
ns2np6 тАФ Represents the stable outer shell electronic configuration for noble gases starting from Neon.
EiтАЛ=high тАФ Represents the high ionization energy required to remove an electron from a stable noble gas.
The stability of inert gases arises from their electronic configuration ns2np6. This configuration results in a very high ionization energy and an electron affinity of approximately zero, making it energetically unfavorable for these atoms to gain, lose, or share electrons to form chemical bonds.
Inert gases are also known as noble gases or rare gases.
They are monatomic and exist as single atoms rather than molecules.
Neon was discovered by Sir William Ramsay and Morris Travers in 1898.
Used in discharge tubes because they are non-flammable and provide bright light.
Chemically stable for use in protective environments.
Limited chemical reactivity makes them difficult to use in conventional synthesis.
Used in neon signs for high-visibility advertising.
Used in cryogenic refrigeration as a liquid refrigerant.
Neon is the second lightest noble gas with an atomic number of 10.
Nitrogen is a diatomic gas (N2тАЛ) that can participate in chemical reactions, especially under high pressure or with catalysts.
Oxygen is a highly reactive diatomic gas (O2тАЛ) that acts as a strong oxidizing agent.
Hydrogen is a reactive, diatomic fuel gas (H2тАЛ) that easily forms bonds with non-metals.
A is correct тАФ Neon possesses a stable octet configuration, making it chemically inert under standard atmospheric conditions.
Always remember that elements in Group 18 are called 'Noble' because they do not participate in the 'common' chemical reactions that other elements do.
