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.
Subtract its electron configuration from the electron configuration of an atom of the element you are given. For sodium, this gives us d^1. 3. Append the symbol of the gas, enclosed in square brackets, to the left side of the electron configuration of an atom of your element. So the noble gas configuration of an atom of sodium is written as [Ne]d^1.
