STABLE ELECTRONIC CONFIGURATION
➢They have 8 valance electrons in their outer most shell except helium.
➢They do not lose or gain electrons to form bonds with other atoms and to form compounds.
➢most of them are Noble gases
➢ examples:- helium (He), Argon (Ar), Neon (Ne), krypton (Kr), Oganesson (Og), Copernicium (Cn), Flerovium (Fl), Dubnium (Db) etc..
UNSTABLE ELECTRONIC CONFIGURATION
➢ they have incomplete valance in their outer most shell
➢ They lose and gain electrons to form bonds with other atoms and form compounds.
➢examples:-sodium (Na), magnesium (Mg), carbon (C), calcium (Ca) etc…
