2. GUIDE CARD 1
Explaining the formation
of ionic bond
Least Mastered Skill:
Sub-Tasks:
o Identify the metallic and non-metallic
elements
o Determine the electronegativity
difference of the given atoms
o Write the Lewis symbol of the given
elements

3. An ionic bond is the electrostatic force holding two oppositely
charged ions together. An ionic bond forms when a transfer of electrons takes
when a transfer of electrons takes place between atoms.
between atoms.
Metals have low electronegativity and ionization energy, thus
and ionization energy, thus they tend to transfer or loose electrons. Non-metals
transfer or loose electrons. Non-metals have high electronegativity and

IONIC BONDDo you know what kind
of element forms cation
and anion after ionic
bonding? Do atoms
attain stability after
ionic bonding?
You will gain
information about
chemical bonding
that involves gaining
and losing electrons
as you explore the
ions with my
adventurous
surprises.

5. ACTIVITY CARD 2
Refer to the Periodic Table of Elements for the electronegativity values. Subtract the
electronegativity values of the metallic element from the non-metallic element.
Encircle the pair/s of elements if the difference is greater than 1.9 wherein complete
transfer of electron/s is possible.

6. ACTIVITY CARD 3
Dots interesting!
Write the Lewis Symbol
of the given elements.
1. Na and Cl
2. Li and F
3. K and O
Since bonding involves
the element’s valence
electrons, Lewis symbols
are used. Lewis symbols
consist of the element
plus a dot for each
valence electron
