Learning Module 2
CHEMISTRY AND THE ATOMIC AND MOLECULAR VIEW OF MATTER
Pre-test:
1
...
1
...
Mendeleev, a
Russian chemist, is known for his work on the Periodic Law and creation of the first
Periodic table in 1869
...
He won the Nobel Prize in Chemistry for the discovery for the periodic system
...
2 Ernest Rutherford (1871 – 1937)
Rutherford was introduced to me when I was grade 11
...
He
discovered the alpha and beta rays, the law of radioactive decay and proposed the
nuclear structure of atom
...
He also received the Nobel Prize in Chemistry for 1908
...
3 John Dalton (1766 – 1844)
Dalton was introduced to me the same way Rutherford was
...
It is
one of the most important theories in all of science
...
He also developed methods to calculate atomic weights and
structures and formulated the law of partial pressures
...
1
...
He is a French chemist and
he was introduced to me as the Father of Modern Chemistry
...
Aside from that, he established the law of conservation
of mass
...
In
addition, Lavoisier discovered that water was a compound made of hydrogen and
oxygen
...
In 1789, Lavoisier wrote the Elementary Treatise of Chemistry
...
1
...
This is
considered one of the solutions to important problems in chemistry
...
Avogadro was also the first scientist to realize that
elements could exist in the form of molecules rather than as individual atoms
...
1
...
He contributed to the understanding of the
atomic structure and quantum theory
...
He used his model to explain the spectral
lines of hydrogen
...
Bohr was introduced to me when I was grade 11
...
7 Robert Boyle (1627 – 1691)
Boyle’s Law is the first thing I remembered from Robert Boyle since I was
grade 10
...
So the pressure and the volume of a gas is inversely
proportional to each other while the temperature and the quantity of gas is constant
...
The Anglo-Irish chemist
also published his most influential writings, The Sceptical Chymist (1661), the first
chemistry textbook and the Origine of Formes and Qualities (1666)
...
8 Henry Moseley (1887 – 1915)
I’ve known Moseley for his contribution in periodic table of elements
...
In
1913 he used self-built equipment to prove that every element's identity is uniquely
determined by the number of protons it has
...
Moreover, he discovered the atomic number of each element
using x-rays that have led to the organization of the elements in the periodic table
...

...
J
...
His plum pudding model is considered one of several historical scientific
models of the atom and first model to represent the atomic structure of matter
...
In 1906, J
...
Thompson
received the Nobel Prize in Physics
1
...
He is also
known for his invention of explosive device and dynamite
...
Nobel used his remaining funds to establish the Nobel Prizes, a set of international
awards given for outstanding works in chemistry, physics, medicine, etc
...
Draw the atomic structure and label its part
...
Neutron – is a particle in the atomic nucleus that has a neutral charge and mass of one
...
Unlike electron and proton,
neutron has no charge
...
Electrons are
extremely small and have an electric charge of −1, which is equal but opposite to the
charge of a proton, which is +1
...
Electrons orbit around
the nucleus the same way planets orbit around the sun
...
It is found in the nucleus of an atom
Electron Orbits – is located in the outside part of atomic nucleus
...

Self-evaluation: How chemistry affect your day-to-day life experiences
...
Chemistry’s just around us
...
For all living things to function and
survived their bodies perform various chemical
processes
...
Everything is made of
chemicals, even our body, but there are chemicals
that are toxic to humans so chemistry teaches me
to be careful, we must be careful
...
Complete the table below
...
Using the fishbone below, fill in the box with the significant events in the development
of Chemistry
...
D
1600s
Boyle
Jābir ibn Hayyān
became one of the first
to use scientific methods
to study materials
...
He developed the
basic ideas for the
behavior of gases
...
Avogadro laid the groundwork for
a more quantitative approach to
chemistry
...
Lavoisier has been considered
to be the “father of chemistry”
...
Volta,
Davy,
Faraday
It would take a large fishbone diagram to cover developments in chemistry since the
beginning and up to today
