Verified step by step guidance1
Identify the atomic number of sodium (Na), which is 11. This means a neutral sodium atom has 11 protons and 11 electrons.
Understand that the Na^+ ion has lost one electron compared to the neutral atom because of the positive charge (+1).
Calculate the number of electrons in Na^+ by subtracting one electron from the neutral atom's electron count: $11 - 1$.
Conclude that the Na^+ ion has 10 electrons.
Remember that the number of protons remains the same (11) because the ionization only affects electrons.
