Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.
The most likely electron configuration for a sodium ion in its ground state is 1s22s22p63s1.
It has 2 electrons in the first shell, and 8 in the second as it gains an electron to form an ion so the configuration is 2,8.
The ions of elements nitrogen (N3-), oxygen (O2-), and fluorine (F-) will have the same electron configuration as a sodium ion (Na+), which is the same as the electron configuration of the noble gas neon.
What symbol would represent a chlorine ion that has ionized to have a stable electron configuration?
