Question
Use the electron configurations of He, Ne, and Ar to explain why these atoms normally do not combine chemically with other atoms.
Step 1
The electron configuration of an atom is the distribution of electrons in atomic orbitals. For helium, the electron configuration is 1s^2. For neon, it is 1s^2 2s^2 2p^6. For argon, it is 1s^2 2s^2 2p^6 3s^2 3p^6. Show more…
