The document discusses the transfer of electrons during chemical bonding and ionic bonding specifically. It begins with an introduction to Lewis symbols and their use in representing valence electrons. It then explains how ionic bonding occurs through the transfer of electrons from a metal to a nonmetal to form ions, using sodium and chlorine as an example where sodium loses an electron to become Na+ and chlorine gains an electron to become Cl-. It further defines ionic bonding as the electrostatic attraction between oppositely charged ions that forms when there is a large difference in electronegativity between the atoms.

3. Review
Review Lewis Symbol. Use the following as your
guide to make a paragraph.
I know that I know something about …
First, …
In addition, …
Finally, …
Now, you know something that I know about …

4. I know that I know something about Lewis
Symbol. First, Lewis Symbol was name after
Gilbert N. Lewis. In addition, it is constructed
by placing dots around the symbol element.
Finally representing the number of valence
electrons surrounding the element in the third
period. Now, you know something that I know
about Lewis Symbol

OF ELECTRONS

8. 1. Select a metallic and a non-
metallic element.
2. Write the Lewis Symbol of the
selected elements.
3. Take note of the electronegativity
value of both elements.
4. Subtract the electronegativity
value of the metallic element of the
non-metallic element.

9. Electronegativity
0.93
Electronegativity
3.16
3.16-0.93=2.26
*If the difference is greater than 1.9, complete transfer of
electron/s is possible.

15. What is ionic bonding?
Ionic bonding is a type of chemical
bonding that involves the electrostatic
attraction between oppositely charged
ions, or between two atoms with sharply
different electronegativities, and is the
primary interaction occurring in ionic
compounds.

16. What kind of element
forms cation after ionic
bonding?
METALS

17. What kind of element
forms anion after ionic
bonding?
Non METALS

18. Why do ions form after
ionic bonding?
Ions form when
atoms gain or lose
electrons.

19. Did the atoms attain
stability after ionic
bonding?
YES
