Explain why atoms such as helium (atomic number 2), neon (atomic number 10), and argon (atomic number 18) do not react with other atoms.
Atomic Number
The number of protons in the nucleus of an atom, determining the chemical properties of an element and its place in the periodic table.
Helium
A chemical element with symbol He and atomic number 2, known for being a lightweight, inert gas widely used in balloons and as a coolant.
Neon
A chemical element with the symbol Ne and atomic number 10, it is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air and is used in fluorescent lamps and signs.

Final Answer :
In these atoms, the outermost energy level has no vacancies; therefore, they do not have to take, share, or lose electrons to fill any vacancies.
