- Alchemy originated as an ancient practice of using symbols and experiments on metals in attempts to prolong life and transform metals like lead into gold.
- Over time, contributions from various civilizations like the Mesopotamians, Egyptians, Chinese, Indians, Arabs and Muslims, and Europeans advanced alchemical techniques and understanding.
- By the 16th century, alchemists had separated into two groups - one pursuing the pseudoscience of immortality and transmutation, while the other helped discover new compounds through scientific experimentation, contributing to the emergence of chemistry as a modern science.
2. Objectives:
(S11/12LT-IIbd-6)
At the end of the lesson, the learners are able to:
Describe the contributions of the alchemists to the science of chemistry
1. Identify the people behind the progression of alchemy to chemistry
2. Perform differentiated activities showing the discovery of
chemistry from alchemy
3. Appreciate the influences of alchemy on the discoveries made
from chemistry
4. What can you observe from these pictures?

MOTIVATION
AncientSymbols Experiments Metals
ALCHEMY ( al–Khemia) = ancient origin of chemistry
= use of symbols and do
experiments on metals
5. 5
The students will
combine the elements
to form at least 5
different substances.
From the resulting
combination, the
students can still add
one element to form
another substance.

MESOPOTAMIANS:
techniques to utilize metals like gold and copper.
They even assigned certain symbols to match
metals with the heavenly bodies such as the Sun
and Moon. They also made use of other materials
such as dyes, glass, paints, and perfumes.
EGYPTIANS:
adapted techniques from the
Mesopotamians and perfected the
use of bronze, dye and glass that
the Greeks later copied.
CHINESE:
had their own processes for
metalwork and ceramic materials,
but they especially focused on
finding minerals, plants and
substances that could prolong life
(elixir of life).

INDIANS:
had a kind of alchemy (rasayana) that looked at
different substances and practices for Vedic
medicine. This is tied closely to Hindu and
Buddhist beliefs. They also perfected the use of
iron and steel and were well-known
manufacturers of dyes, glass, cement, solutions
for textiles, and soap.
MUSLIMS AND ARABS:
Scholar Jabir Ibn-Hayyan (Geber)
translated the practices and
Aristotelian thinking of the Greeks
and wrote extensively on how
metals can be purified. He came up
with the preparation of acids such
as nitric, hydrochloric and sulfuric
acids, as well as aqua regia (nitro-
hydrochloric acid).
EUROPEANS:
Paracelsus believed the human
body works alchemically and
proposed the three essentials or
tria prima: salt, mercury and sulfur
to maintain balance on health He
used inorganic salts, minerals and
metals to treat illnesses.

to change metals into gold and the
“elixir of life” as means of prolonging
life

Modern Chemistry
Researches
University of California–San
Francisco biochemists identified a
memory-boosting chemical in
mice, which might one day be
used in humans to improve
memory.
Cheaper clean-
energy technologies
could be made
possible thanks to a
new discovery by a
professor of
chemistry at Penn
State University.
The Duke Cancer
Institute found that
an osteoporosis
drug stopped the
growth of breast
cancer cells, even in
resistant tumors.
These are just a few examples of how
modern chemistry carries on the
alchemical quest for the elixir of life

17. Trivia!!
Lead into Gold???
The Power of PowerPoint | thepopp.com 17
Lead (atomic number 82) and gold (atomic number 79) are
defined as elements by the number of protons they possess.
Changing the element requires changing the atomic (proton)
number.
The number of protons cannot be altered by any chemical
means.
However, physics may be used to add or remove protons and
thereby change one element into another. Because lead is
stable, forcing it to release three protons requires a vast input
of energy, such that the cost of transmuting it greatly
surpasses the value of the resulting gold.
Good news! It was already achieve in Siberia!
