2. What’s an element?
Remember…. A pure substance….that can
not be broken down into another
substance…..
Name 5 elements?
3. Pod Discussion: Do you think
elements combine? Explain your
thinking…. provide evidence?
Salt Water Sugar
4. Compound
Pure substance composed of two or more different
elements joined by chemical bonds.
These chemical bonds can only be separated by other
chemicals. You can not physically pull, cut, or tear a
compound apart.
Made of elements in a specific ratio .
5. What does ratio mean?
How much of one
thing is compared to
another.
6. Compound CO is a deadly
compound… What
two elements is it
made from? What is
the ratio of
elements?
Carbon and Oxygen
Waste gas from an
engine.
Carbon Monoxide
14. Compound N2O is a common
compound… What
two elements is it
made from? What is
the ratio of
elements?
Nitrogen Oxygen
Nitrous Oxide
Laughing Gas

16. Pod Discussion: What’s the
difference between an element
and a compound?
An element contains just one type of atom.
A compound contains two or more different
atoms joined chemically in a ratio.
34. Compound Discovery
It is the year 2032 and you and a partner have just been asked to join
NASA on a trip to Jupiter. On this trip, your team discovered a brand new
compound that no one has ever seen. Upon further investigation, you
also noticed the compound was made up of elements commonly found
on the periodic table and ones that have also never been seen. To
introduce the world to the new compound, you need to chart the
following information:
Name of Compound
Colored Picture of the discovered compound
Description of the physical and chemical properties of the
compound
List of all of the elements that are bonded together to make up
the compound (minimum of 2, real or made up)
Atomic #, Atomic Mass, Protons, Neutrons and Electrons written
out for each element
Atomic Drawing of the compound. Showing how each element
bonds to the other (Protons, Neutrons and Electrons) (Each
Element wants 8 electrons in their outer roadway, so they
may share electrons/Bond)
