Learning
Competency/ies:
The learners
1. cite the contributions of J.J. Thomson, Ernest
Rutherford, Henry Mosely, and Niels Bohr to the
understanding of the structure of the atom
(S11/12PS-IIIb-9);
2. describe the nuclear model of the atom and the
location of its major components (protons,
neutrons, electrons) (S11/12PS-IIIb-10);
3. explain the concept of the atomic number led to
the synthesis of new elements
(S11/S12PS-IIIb-11);
4. write the nuclear reactions involved in the
synthesis of new elements (S11/12PS-IIIb-12);
5. cite the contribution of John Dalton toward the
understanding of the concept of the chemical
elements (S11/12PS-IIIb-13); and
6. explain how Dalton’s theory contributed to the
discovery of other elements (S11/S12PS-IIIb-14).

Understanding how the concept of the atom evolved from Ancient Greek to the present
a. analyze how the model of an atom changed over time;
b. illustrate how the different models help us better understand the concept of atomic
model; and
c. explain how new elements are synthesized.
The idea of the atom along with the idea of the elements evolved

4. Procedures
4.1 Introductory Activity
(10 minutes)
4.2 Activity/Strategy
4.3 Analysis
(15 minutes)
4.4 Abstraction
4.5 Application
(15 minutes)
The teacher will have a recap on the Greeks’ concept of the atom, contributions of
the alchemists to the science of Chemistry and the discovery and structure of the
atoms.
The teacher will have an interactive lecture on how the the model of an atom
changed over time:
1. John Dalton
2. J.J. Thomson
3. Ernest Rutherford
4. Niels Bohr
After knowing the contributions of the scientists mentioned above, the students will
then illustrate the structure of the nuclear model of the atom citing the location of
its major components (electron, proton and neutron).
The teacher will proceed to a lecture-discussion on atoms, atomic number and
atomic mass.
Using the interactive video on Chernobyl Nuclear Element Incident, the students
will answer an activity on “Bomb Leftovers” which will deal with the synthesis of
new elements (Radioactivity).

4.6 Assessment
(15 minutes)
A paper and pencil quiz shall be given to assess the students.
4.7 Assignment
(This only be given as the need arises.)
4.8 Concluding Activity
(5 minutes)
(See appendices below.)
The teacher will ask the students to give THUMBS UP sign if they have learned
and a THUMBS DOWN if they haven’t really grasped the major concepts about the
CONTRIBUTIONS OF DALTON, THOMSON, RUTHERFORD AND BOHR IN
UNDERSTANDING THE ATOMIC STRUCTURE, NUCLEAR MODEL OF THE ATOM AND
SYNTHESIS OF NEW ELEMENTS.
