Out of Na and Na+ which one has larger size and why?

 Na has 11 electrons from which 1 electron is in the last orbit and having three orbit K,L,M, but when it becomes Na+ it means 1 electron is removed from its outermost orbit that is M then it would have now  orbit K,L which are two thus Na has larger size THAN Na+

Na+ is smaller than Na because, it has given away one electron because of which the electron shielding gets stronger due to more protons and less electrons. Whereas, Cl- is larger than Cl because it has gained an extra electron and so, the no.of electrons increase thus extending the attraction to one more, leading to decreases nuclear attraction .
Hope this helped! Cheers!

Na because it the large electron confriguration than Na+ ion makes their electron confriguration is as like Neon .

Which of the following have large size (Ca,Ca+.)
  • 2
in Na + ion as it has lost one electron,due to decrease in no of shells,the effective nuclear charge increases leading to decrease in atomic size.hence Na atom will be larger

Ca has large size

Na has greater size than Na+ because Na has more number of shell than Na+ as it is characteristic of atomic radii
