Word Sort – Your task…1. Create a T – Chart in your notes that looks like this…
Compound Mixture
2. Sort the words & write them into the correct column – Mixture or Compound – Please # your words.
3. Underneath the word write in 1 sentence WHY it is a compound or mixture.
2 points for correct placement (50 pnts. total), 2 points for sentence WHY (50 pnts. Total).
Total value: 100 points

LEQ #4: How does the property of a metal make it good for use in cookware as opposed to a nonmetal?
Ms. Kirkpatrick wants to make pasta for dinner. In 30 seconds, list ALL the materials she would need to cook the
pasta.
What kind of pan would Ms. Kirkpatrick use? Why?
Take away Point:* Elements from Groups 1 and 2 often bond with Elements from Groups 16 and 17
HOT Q: WHY????
Guided Notes • Elements in the same group share similar
chemical properties
• The elements in the 18 groups of the periodic table are also classified into three larger categories – metals, non-metals & metalloids.
• These categories are based on general properties that elements share
Guided Notes Continued…• Metals: A metal is an element that is a good
conductor or carrier of heat and electricity– 75% of the elements are Metals
• Non-Metals: A non-metal is an element that is not a good conductor of heat and electricity – About 24% of the elements are Non-Metals
• Metalloids: A metalloid is an element that conducts electricity only under certain conditions – Has properties of both metals AND non-metals– Only 8 elements are metalloids – Also known as a semi-conductor
Let’s Revisit the Periodic Table !• All elements can be divided into three
categories:
–METALS
–NONMETALS
–METALLOIDS

There has been a string of crimes in the Charlotte area…
It’s up to YOUR team to figure out what happened.
Put on your detective caps!
What will you need?
• A crime report hand out• A periodic table• Your class notes
