The noble gas you would use to write the configuration for the chlorine ion would be neon (Ne) which has an atomic number of 10. This symbol, written inside square brackets [Ne], represents 10 inner core electrons.
The only chemical elements which are stable single atom molecules at standard temperature and pressure (STP), are the noble gases. These are helium, neon, argon, krypton, xenon and radon. The heavier noble gases can form chemical compounds, but the lighter ones are non-reactive or inert. For example, helium, being the simplest noble gas, has only two electrons, thus meaning it is satisfied with a complete outer shell, making it relatively non-reactive, hence it is a noble gas.
