Chemistry

Ionic Bonding is the transfer of electrons. 

      - The atoms transfer electrons to form positvley or negativley charged atoms, called ions. 

      - Because of the attraction of opposite charges +,- , the ions are the strongly attracted to each other.

Groups 1,2,6,7, are most likely to form ions. 

Groups 1 and 2 are metals and they lose electrons, to form positive ions or cations.

Groups 6 and 7 are non - metals. They gain electrons, to form negative or anions. 

Only elements on the opposite sides of the periodic table will form ionic bonds, and example is when sodium and cholrine form.
