The important thing shell could be the outermost one, called the valence shell. If this outermost shell is finish, or filled with the maximum amount of electrons for that shell, the atom is secure, with little if any tendency to interact with other atoms. But atoms with incomplete outer shells find to fill or to vacant such shells by gaining or dropping electrons or by sharing electrons with other atoms.
