Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions. For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion.The cations are positively charged ions while the anions are negatively charged ions. To form a cation, a neutral atom has to donate its electrons. But for the anion formation, the atom gains the electrons. Cations attain stability by losing the electrons while the anions complete their octet by gaining the electrons.
