D. Specific At the end of the lesson, the learners will be able to:
Learning
Outcomes 1. Define electronegativity
2. Find the electronegativity of elements in the periodic table
3. Explain the VSEPR theory
4. Draw the geometry of molecules using the VSEPR theory
5. Distinguish between polar and non-polar molecules
6. Relate the properties of molecules to its polarity.
II. CONTENT
BOND POLARITY:
-Polar covalent bond
-Non-Polar covalent bond
E. ELABORATE Have the learners familiarize
themselves with the periodic table.
Let them find the EN value of several
elements. Have them determine the
most electronegative element and
the least electronegative element.
Explain Electronegativity; the ways to
determine its polarity and dipoles.

G. EXTEND Watch a five-minute video showing
the five different geometric shapes
under the VSEPR theory, namely,
linear, trigonal planar, tetrahedral,
trigonal bipyramidal, and octahedral.
The video also explains the basic
principle behind the VSEPR theory.
