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

Compoundwrite 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 elements?

Carbon and OxygenWaist gas from an engine. Carbon Monoxide

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.

Compound DiscoveryIt 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)
