Answer 2

Cesium and Neon

Step-by-step explanation:

Remember, Neon is a noble gas, also called an inert gas. It does not react really to form compounds. Although chlorine is only one column to the left of neon, it is very reactive and ready forms a salt when combine with sodium. The other elements have similar reactivities to each other. Only Neon is a non-reactive choice.
