Sodium Ion (Na+): Understanding Electron Configuration

A sodium ion (Na+) has 10 electrons. Here's why:

* Neutral Sodium: A neutral sodium atom has 11 electrons.

* Ionization: To become a positive ion (Na+), sodium loses one electron.

* Result: This leaves 11 - 1 = 10 electrons in the sodium ion.
