In the name of the Father, the
Son, and the Holy
Spirit.""""""".. Amen.
(Students look around,
picking up trash and
organizing their chairs.)
Good morning, Ma'am. We're
fine.
Okay, Ma’am
Yes, Ma’am.
We have discussed valence
electron Ma’am.
These two terms, class are widely
important in chemical bonding.
The video shows chemical

3. Correct, the two different videos show two different ways an
electron participates in bonding. What do you think our topic for
discussion in class?
Very good today, we will be discussing the different types of
chemical bonding. At the end of our discussion, you are expected
to:
a.State the difference between ionic, covalent, and metallic
bonds.
b.Classify compounds as either ionic, covalent, or metallic
properties determine the properties, which and
c.Explain the importance of knowing the types of compounds
and their properties in real life.
C. Analysis and Discussion
To understand this further the type of chemical bonding, let us
recall the groups in the periodic table. The periodic table is
divided into three segments in terms of the metallic property of
the elements. From this illustration, what are the three categories
of elements in terms of their metallic properties?
Excellent! We have metals, metalloids, and non-metals. Now,
let's review the basic properties of metals and non-metals. Who
can share some characteristics of metals?
Great! Metals generally have high conductivity, malleability, and
ductility. What about non-metals?
Correct! Non-metals tend to have lower conductivity, are often
brittle, and are not malleable. Now, as we move forward, let's
define the term "chemical bonding" more precisely. Gian, could
bonding, Ma’am.
The video demonstrates various
ways the electron is being shared
to form chemical bondschange
Our topic will be about types of
chemical bonding, ma'am
Metals, non-metals, and
metalloids, Ma’am

4. you please share your definition again?
Perfect! Now, let's discuss the types of chemical bonding. The
videos we watched demonstrated the chemical bonding of two or
more atoms of an element. Fiona pointed out that the videos
showed different ways electrons participate in bonding. Based on
this, what do you think are the major types of chemical bonding?
Exactly! We'll be covering ionic, covalent, and metallic bonds.
These bonds play a crucial role in determining the properties of
compounds.Let’s start with ionic bonding. The first video that
you have seen is an example of ionic bonding. Who can tell me
what ionic bonding is? Kia?
Correct, ionic bonding is also called an electrovalent bond. It
involves the complete transfer of valence electrons from one
atom to another. Due to the transfer of electrons, it can produce
two oppositely charged ions. Now, each type of bond exists for a
specific type of group of elements based on their chemical
properties. Let’s try to identify the type of elements present in an
ionic bond. Hanz, can you tell me?
To which group do they belong?
Excellent, what does it imply for ionic bonds?
Chemical bonding refers to the
formation of a chemical bond
between two or more atoms or
molecules to form a compound.
Ionic, covalent and metaalic
Ma’am
Ionic bonding involves the
transfer of electrons.
Na and Cl Ma’am
Na is a metal while S is a non-
metal.

5. Very good, an ionic bond exists between a nonmetal and a metal.
Now, can you identify the elements that can form ionic bonds?
What else?
Let’s consider the formation of NaCl. Let us identify which
element has the tendency to lose, accept, and attract electrons.
Which of the two is more likely to lose an electron?
Very well, how about the one that will accept valence
electrons?""
Now as the elctron is being transferred
from Na to Cl what happens to the
valence electron of the two element?
Excellent, class is what you have noticed. As they form a bond,
both of them achieve stability. In addition to that, they have what
we call the electrostatic force that holds them together. Now, as
Na and Cl lose and gain electrons, they become more and less
positive/ negative. Creating what we call an anion and cation.
Which element do you think became more negative?
Excellent! Cl becomes more negative due to its higher electron
affinity. As a result, both elements achieve stability, having
completed their valence electron shells. Here is the Lewis dot
structure of NaCl
Ionic bonds exist between a metal
and a non-metal.
Be and O
Mg and C
Na Ma’am.
Cl Ma’am due to it having high
electron affinity, ma'am.
It became 8, Ma’am, which
means that the two elements are
already stable.
Cl becomes more negative and
Na becomes more positive

6. Let’s try this one, KF
From the knowledge that we gained in class, can you describe
the properties of an ionic bond?
Correct. How about in terms of melting point?
Now, let's move on to covalent bonding. Who can define
covalent bonding for us? Gian?
Correct! Covalent bonding involves the sharing of electrons
between two nonmetal atoms. Unlike ionic bonding, where
electrons are transferred, covalent bonds result from the mutual
sharing of electrons. This sharing allows both atoms to achieve
a stable electron configuration.
Now, let's consider an example of a covalent bond. In the
second video, you observed a different type of bonding. What
can you say about the way electrons are shared in covalent
bonds, Fiona?
The bond is strong, ma'am.
It has a high melting point,
ma'am, due to its strong
connection.
Covalent bonding is the type of
bonding in which two non-metals
share electrons.

7. Exactly! In covalent bonds, electrons are shared in pairs
between two nonmetal atoms. This sharing creates a bond that
holds the atoms together. Covalent bonds are also called
molecualr bond class.
To understand this better, let's look at the example of the
fluorine molecules F2.
Let us look at the molecule of water. What can you observe?
Great explanation! In the water molecule, each hydrogen atom
shares one of its electrons with the oxygen atom, forming a
covalent bond. This sharing allows all the atoms to achieve a
stable electron configuration. In addition, class of covalent
bonds, we have what we call bond order. This bond order is the
number of bonding pairs of electrons between two atoms.These
are the types of bonds in a covalent bond
Covalent bonds class results in colvalent compound, which is
basically made up of two.
Non-metal compound. How can we describe the properties of
covalent compounds?
The two-atom elements shared
electrons and became stable,
ma'am.
Low melting point, ma'am, but
they are not good thermal and
electrical conductors.
Metallic bonding is the type of
bonding that forms metals, and it
occurs between two metal atoms.

8. In addition, a covalent bond can be further classified as a polar
or non-polar molecule. The difference between the two lies in
the sharing of molecules. Polar compounds have uneven sharing
of electrons while non-polar has equall sharing of molecules.
Correct,they have lower melting points and boiling points than
ionic compounds because covalent bonds are weaker than ionic
bonds. They do not conduct electricity because they do not have
free ions or electrons to carry a charge. They are usually gases or
liquids at room temperature because the intermolecular forces
between covalent molecules are weak.
Now, let's move on to metallic bonding. Who can define
metallic bonding for us? Kia?
Exactly! Metallic bonding occurs between metal atoms. In this
type of bond, electrons are delocalized and free to move within
the metal structure. This gives metals their unique properties,
such as conductivity and malleability
In addition, there are other ways to classify compounds which
are based on their electronegativity. What we need to do is to
subtract the electronegativity of two elements and look at the
electronegativity difference.
Any questions about this class?
GENERALIZATION
Now, let's take a moment to compare and contrast ionic,
covalent, and metallic bonds. Can someone highlight the key
differences between these three types of bonds?
Non-so far, Ma’am.

9. Fundamental ideas in chemistry, such as ionic, covalent, and
metallic bonding, explain the various ways in which atoms
interact to produce stable molecules.
Ionic bonds form when an electron is transferred from a metal
(generally found on the left side of the periodic table) to a non-
metal (usually found on the right side). This process produces
positively charged ions (cations) and negatively charged ions
(anions) as the metal gives up one or more electrons to the non-
metal. Strong bonds are formed by the electrostatic attraction
between these oppositely charged ions, as demonstrated by
substances like sodium chloride (NaCl), in which sodium gives
an electron to chlorine.
Let's reinforce our understanding with a quick exercise. I'll give
you a compound, and you tell me which type of bond it is most
likely to form. Ready? How about HCl?
Very good, it is a non poar covlant bond. HCl is a compound
formed through covalent bonding because hydrogen and chlorine
are both nonmetals.
Now, let's consider NaBr. What type of bond is likely to form
between sodium and bromine?
Exactly! NaBr is likely to form an ionic bond because sodium is
a metal, and bromine is a nonmetal.
Let's do one more. How about Fe2O3?
Great job! Fe2O3 is likely to form an ionic bond because iron
Ionic bonds are created when a
metal transfers electrons to a non-
metal, creating ions with
opposing charges. Conversely,
covalent bonds are formed when
two non-metals share electrons to
form a molecular bond. Last but
not least, metallic bonds arise
between metal atoms, causing the
electrons to become delocalized
and giving metals special
characteristics.
Covalent bond, ma'am

What is the importance of knowing the type of bond that exists
in a compound class?
Now, class, remember the importance of knowing these types of
bonds in real life. Different materials around us have specific
properties based on the type of bonding they exhibit.
Understanding these properties helps us use materials effectively
in various application
