30 views

Noble gases within the first 20 elements are Helium (He), Neon (Ne), and Argon (Ar). These gases are known for their inert properties and lack of reactivity due to their fully filled electron shells.

FAQs & Answers

  1. What makes noble gases inert? Noble gases are inert because they have fully filled electron shells, which makes them stable and unlikely to react with other elements.
  2. Which are the noble gases found in the first 20 elements of the periodic table? The noble gases among the first 20 elements are Helium (He), Neon (Ne), and Argon (Ar).
  3. Why are Helium, Neon, and Argon classified as noble gases? They are classified as noble gases due to their lack of chemical reactivity and stable electron configurations.
