Break Down the Problem

1. We need to identify the elements with atomic numbers 10, 18, 36, 54, and 86.
2. Determine the group of elements based on their classification in the periodic table.

Relevant Concepts

• Atomic Numbers and Element Classification:
  • Atomic number 10 corresponds to Neon (Ne).
  • Atomic number 18 corresponds to Argon (Ar).
  • Atomic number 36 corresponds to Krypton (Kr).
  • Atomic number 54 corresponds to Xenon (Xe).
  • Atomic number 86 corresponds to Radon (Rn).

Analysis and Details

1. Element Identification:
   • Ne (10): Inert gas
   • Ar (18): Inert gas
   • Kr (36): Inert gas
   • Xe (54): Inert gas
   • Rn (86): Inert gas

All of these elements are classified as noble gases, which are non-reactive gases found in Group 18 of the periodic table.

Verify and Summarize

• Since all mentioned elements belong to the same group in the periodic table and share similar properties, they can be summarized as inert gases.

Final Answer

The elements with atomic numbers 10, 18, 36, 54, and 86 are all inert gases.
