Neon.
explanation:- A Na atom contains 11 electrons
=> a Na(+) ion contains 11-1 = 10 electrons.
=> the reqd inert gas must have the atomic no 10
=> its Neon(Ne)(atomic no =10)

I checked the Periodic Table of Elements and found that Sodium (Na) has 11 electrons when stable.
As an Ion, it has lost an electron and becomes Na+ which has 10 electrons.
This corresponds to Neon (Ne), Noble gas with 10 electrons.
(This is the ONLY similarity of the two elements).

Sodium ion = Na+ which has one less electron than it's elemental state = 11 - 1 = 10.
Hence the noble gas with 10 electrons on the periodic table is neon (atomic no = electron no. = 10)

Neon has 10 e-, as the same as Na+.
The at. no of Na is 11, 11-1 = 10 which is the at. no. of Ne.
