Atoms attain Noble gas configuration by gaining or losing electrons.
During the process of exchanging electrons, atoms turn into ions namely, Cations and Anions.
In this case, the atom which has two more electrons than the Noble gas configuration, is a Cation.
Cations are basically positively charged ions, which are usually attracted to cathode during the process of electrolysis.
