Atom without a stable octet?
Atom without a stable octet?
An atom of sodium (Na) does not have a stable octet because it needs to lose one electron to achieve a stable electron configuration.
Formation of ionic compounds?
Formation of ionic compounds?
Ionic compounds are formed when metals react with non-metals, resulting in the transfer of electrons and the formation of ions.
