When a sodium atom reacts with a chlorine atom to form a compound, the electron configuration the ions forming the compound are the same as those in which noble gases?
Metals are electron rich..............
The valence electrons of metals tend to be lost, and for this reason metals TEND to be reducing. And non-metals are electron poor. And as a result they tend to be oxidizing. (This tendency is another manifestation of electronic structure.)
Sodium metal and dichlorine thus tend to be involved in redox phenomena:
Given the electronic configuration of the reactants, this redox transfer means that each species shares the electronic configuration of it nearest inert gas neighbourL i.e.
And please look at the Periodic Table to confirm these configurations.
