The noble gases include helium, neon, argon, xenon. What do their electron configurations have in common? Answer choices:
a- In the highest occupied energy level, the s sublevel is filled and the p sublevel is empty.
b- In the highest occupied energy level, the p sublevel is half-filled.
c- In the highest occupied energy level, the s and p sublevels are completely filled.
d- In the highest occupied energy level, the s sublevel has one electron.

Many free radicals combine to form molecules that do not contain any unpaired electrons. the driving force for the radical–radical combination reaction is the formation of a new electron‑pair bond. consider the chemical equation. n(g)+no(g)⟶nno(g) n(g)+no(g)⟶nno(g) write lewis formulas for the reactant and product species in the chemical equation. include nonbonding electrons. n(g)n(g) select draw rings more erase select draw rings more erase select draw rings more erase n no(g)
