Which of these elements on the Periodic Table is a Noble Gas?

  • Colbalt
  • Potassium
  • Iodine
  • Neon
Explanation

The element Neon (Ne) is a noble gas. Noble gases are known for their extremely low reactivity due to having a complete outer electron shell. In the case of Neon, it has a full complement of 10 electrons, meaning it is very stable and does not readily form compounds with other elements. This lack of reactivity makes noble gases like Neon useful in various applications, such as in lighting, lasers, and in filling balloons for their non-flammable properties.
