Element vs
Compound
Mini Lesson
What’s an element?
 Remember….
A pure substance….that
can not be broken down into another
substance…..
 Name 5 elements?
Pod Discussion: Do you think
elements combine? Explain your
thinking…. provide evidence?
Salt
Water
Sugar
Compound
write this down in your ISN
 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 .
What does ratio mean?
How
much of one
thing is compared
to another.
Compound
CO is a deadly
compound… What
two elements is it
made from? What
is the ratio of

Pod Discussion: What’s the
difference between an
element and a compound?
element contains just one type of atom.
 A compound contains two or more different
 An
atoms joined chemically in a ratio.

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)
