1. Consider the ELECTRONEGATIVITY of
metal atoms vs non-metal atoms

2. Ionic Bond 2 step process: # electrons lost by cation(s) MUST =
occurs between: metal & non-metal atoms
2 step process:
1st step: formation of +/- ions
transfer of electrons from metal to non-metal atoms
2nd step: formation of ionic bond
electrostatic attraction between +/- ions forms bond
# electrons lost by cation(s) MUST =
# electrons gained by anion(s)

3. group 1 elements are most reactive metals so what group _
group 1 elements are most reactive metals so what group _?_ of non-metals will easily take the 1 val e- electron from these alkali metals ?
how about the group with 7 val e- since they need one more e-?
group 1 metals readily react with group 17 non-metals!

4. Na metal
(g)

6. Consider the ELECTRONEGATIVITY of non-metal atoms

7. Covalent Bonding results from: electrostatic attraction between
(+) charged protons in nucleus one non-metal atom
AND
(-) charged e- of neighbor non-metal atom

8. covalent bond is formed between 2 non-metals if:
attractions are > than repulsions

9. since there is not a large difference in electronegativity difference between non-metal atoms:
electrons are SHARED, not transferred
