What is Chemistry?
The branch of science concerned with the
properties of substances and the interactions
between different types of matter.
Using detergents
to clean clothes
Determining which medication is
appropriate and the dosage
Cooking and
baking
What is Chemical Engineering?
• Applied chemistry
• Engineering concerned with design,
construction and operation of machines
that perform chemical reactions,
separations/mixing and fluid flow to solve
problems and make useful products.
What’s an Atom?
The smallest unit
of a chemical
element that
contains all
properties of that
element
Components of an Atom
Nucleus
The center portion of an atom
containing the protons and
neutrons
Protons
Positively charged atomic
particles
Neutrons
Uncharged atomic particles
Electrons
Negatively charged atomic
particles that orbit the nucleus
What is an Element?
A pure substance, composed of only one
Periodic

of
Elements
type of atom.
What is a Molecule?
• 2 or more atoms bonded
together, sharing
electrons
• Small particles that make
up all living and non-living
things
• Each molecule has a
unique arrangement that
allows it to interact with
other molecules
What is the difference between a
chemist and chemical engineer?
Chemist
A chemist studies chemicals, matter and its
properties, and atoms in order to understand
how elements join together to form different
substances.
Chemical Engineer
Works in collaboration with chemists to
develop chemicals for useful purposes.
What does a chemist do?
• Chemists study atoms and how they join
together
• Chemists use their knowledge of how
atoms combine to discover new products
• Chemists work to develop new drugs to
treat diseases
• Chemists also work in the oil industry to
find better ways to refine oil to make fuel
burn cleaner
