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 configurations are as follows: $$\begin{array}{l}{H e-1 s^{2}} \\ {N e-1 s^{2} 2 s^{2} 2 p^{6}} \\ {A s-1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6}}\end{array}$$ Show more…

Atoms form ions so as to achieve electron configurations similar to those of the noble gases. For the following pairs of noble gas configurations, give the formulas of two simple ionic compounds that would have comparable electron configurations. a. [He] and [Ne] b. $[\mathrm{Ne}]$ and $[\mathrm{Ne}]$ c. [He] and [Ar] d. $[\mathrm{Ne}]$ and $[\mathrm{Ar}]$
