Introduction To Chemistry
The study of composition of matter and the changes that 1. All matter is made up of atoms that are too tiny to see by the
matter undergoes. naked eye & can’t be broken down further into smaller portions.
Explains the natural world. 2. Atoms are in constant motion around an empty space that
Prepares people for career opportunities. they called void.
Produces informed citizens. 3. Atoms are completely solid. [ false ]
4. Atoms are uniformed with no internal structure.
TWO DIVISION OF CHEMISTRY
5. Atoms can come in different shape and sizes. [ true ]
Pure Chemistry - research driven by facts and theories
Applied Chemistry -application of pure chemistry. Epicurus of Samos - popularized atomism.
- Developed the ideas of Leucippus and Democritus.
FIVE TRADITIONAL AREAS OF STUDY
- According to him atoms have diffeferent weights, same
Inorganic chemistry -study of chemicals that do not
speed regardless of its size.
contain carbon. ( diamond, sulfur, silver)
- Plato and aristotle opposed his ideas.
Organic chemistry -all about carbon based compounds.
Empedocles - a certain matter is composed of only four
( Alcohol, Polymers, Vitamins, Human, Coal, Methane )
elements. Plato and Aristotle agreed with him.
Analytical Chemistry - study of the quality and quantity of
Aristotle - continuous theory that matter can be divided
components of different substances.

Biochemistry- study of the living system or the living

things or anything that has life. (biomolecule, lipids)
All theories are based on logic
Physical chemistry - study of the mechanism, rates, and
energetics of chemical reaction. 5 STATES OF MATTER
1. Bose-Einstein condensate - is a very odd condition in which

all atoms atain the same quantum-mechanical state. This state is
The earliest belief of the Greek philosophers was that
matter is just a single element. only found within a minute portion of absolute 0.
2. Solids - are materials with a defined volume and shape.
GREEK PHILOSOPHERS Resistant to outside forces, tend to keep their shape and mass.
CHANGES IN MATTER
Physical changes - the composition of the material does
not change; may or may not be reversible.
Chemical changes - chemical reactions; new product =
new composition; represented by chemical equation.
- Reaction - Products; Mass of products = mass of
reactants ( Law of Conservation of Mass)
