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.
