Which one between Na and `Na^(+)` would have more size ?

Explanation

(1) the atomic number of sodium is 1 and it has 11 protons and 11 electrons with outer electron as `3S^(-1 ) ` whereas `Na^(+)` ion has 11 proptons only 10 electrons
(2 ) The 3s shell of `Na^(+)` has no electron in it .
(3 ) so the outer shell configuration is `2s ^(2) 2P^(6) `
(4) AS proton number is more than electrons it if ,. the nucleus of `Na^(+)` ion attracts outer shell electrons with strond nuclear force .
(5 ) as a result the `Na^(+)` ion shrinks in size .
(6 ) Therefore , the size of `Na^(+)` ions is less than Na atom .
