something that is not
matter?

which an element can
be divided and still be
the same element
• Building blocks of
matter.
• Make up everything
around you.
• Too small to be seen.
Objective: I will be able to describe and identify
the parts that make up an atom.
What is Matter Composed of?
Objective: I will be able to describe and identify
the parts that make up an atom.
What is an Atom composed of?
• Parts of the Atom
– Subatomic particles
• Nucleus – small dense center
of the atom.
– Protons = Positive Charge
– Neutrons = Neutral Charge
• Electron Cloud- surrounds the
nucleus
– Electrons = Negative charge
Objective: I will be able to describe and identify
the parts that make up an atom.
Elements
Objective: I will be able to describe what an
Element is & explain how to use the Periodic Table.
What is an Element?
• Element
– A substance composed of
a single kind of atom.
Objective: I will be able to describe what an Element is
and explain how to use the Periodic Table.
What is an Element?
• Atomic Number
– Identifies the Element
– Determined by the
number of Protons.
• = # of Electrons.
• Example:
– Cl (Chlorine)
• Atomic Number = 17
• # of Protons? =
Objective: I will be able to describe what an
Element is & explain how to use the Periodic Table.
What is the Periodic Table?
Chemical Symbol
•1-2 letter abbreviation
•1st letter capitalized
•2nd always lowercase

What is the Periodic Table
Objective: I will be able to describe what an Element is
and exiplain how to use the Periodic Table.
What is the Periodic Table?
• Periodic Table
– Developed by Mendeleev
– Arranges elements by Atomic Number
• Revealed Patterns
I will be able to define and describe the differences
between compounds and mixtures.
What is a Compound?
• Compounds
• A substance made up
of different kinds of
atoms chemically
combined.
– Have different
properties than the
elements they are
composed of.
– Example:
» NaCl (salt)
I will be able to define and describe the differences
between compounds and mixtures.

between compounds and mixtures.
What is a Mixture?
• Mixtures
– Two or more
substances that are
combined physically,
not chemically.
