1. Metals form cations after ionic bonding because they completely transfer/give away electrons.
2. Non-metal form anions after ionic bonding because they attract electrons toward themselves.
3. Ions form after ionic bonding because this type of bond involves complete transfer of electrons.
4. Yes, after ionic bonding the participating atoms attain the stable electronic configuration of the nearest noble gas.
5. Ionic bonding will take place between a metal and nonmetal with electronegativity difference of greater than 1.9
6. Not all metal and nonmetal combinations will result to ionic bond. Only those with electronegativity difference of more than 1.9 will result to an ionic bond.
7. No, because the electronegativity difference is below 1.9. [1.5 (Al) -3.0 (Cl)= 1.5]
That's my answer :))) Ayos lang kahit wag mo nang kopyahin yung nakaparenthesis sa no.7 ^__^
