Metals usually have upto 3 electrons in their outer most shell (in non transitional elements). To achieve the noble gas configuration they would release these electrons and become positive ions.
Non metals in the other hand (mainly group V,VI,VII elements in the periodic table) has 5, 6 or 7 electrons in their outermost shell. In order to achieve a stable electronic configuration these elements can accept electrons and become negative ions. Electrostatic attraction between a positive ion and a negative ion makes ionic bonding.
compounds with ionic bonds are having properties such as high melting points, boiling pointsand readily soluable in water .
