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 He+ ion (helium ion) has the same electron configuration as an atom of helium (He) because it has lost one electron, making it a 1+ ion. Both the helium atom and He+ ion have a total of 2 electrons arranged in the 1s orbital.
What symbol would represent a chlorine ion that has ionized to have a stable electron configuration?
