2.1: Elements and Compounds
Objective (SWBAT):
 Define matter
 Compare an element and a compound by sorting examples into the appropriate pile
On Your Desk:
Expectations:
 This packet
 Students will work quiet and respectfully.
 Writing utensil
 Students will raise their hand before speaking.
 Calculator
 Students will sit at SLANT.
 Teacher will respect and encourage all questions.
 Teacher will enforce all rules and expectations.
Do Now: Answer the following questions on a separate piece of paper to turn in to Ms. Carney.
1. Think back to the entire first unit (Measurement). What did you like about the unit? (It can be
anything: labs, activities, etc.)
2. What would you have wanted to have been done differently?
3. What could you specifically have done differently? (It could be behaviorally or academically)
Chemistry Terminology (I do)

Element/Compound Card Sort Activity (We do)
Directions:
 With your partner, sort the cards into two categories, Element or Compound. Be sure to justify
your answer.
 If you finish early, create your own examples on the blank cards.

44 Most Common Elements (I do)
http://www.youtube.com/watch?v=ssaUusY6hWM&feature=related
The names of chemical elements come from many sources. Often an element’s name is derived from a Greek,
Latin, or German word that describes a physical property of the element. For example, gold was originally
called aurum, a latin word meaning “shining down” and lead was known as plumbum, which means heavy.
 Element names vs. Symbols: Scientists like their discussions to be concise and clear. In order for
our chemical discussions to flow, you MUST memorize BOTH the names and symbols of the 44
most common elements. See the list below.

Most elements use the first letter (or two
letters) in their names as the chemical
symbol.
This makes remembering (or even guessing) most
chemical symbols easy.
Example 1: Hydrogen’s first letter is H. What is its
chemical symbol?
Example 2: Barium’s first two letters are Ba.
What is its chemical symbol?
Every family has someone who doesn’t follow the rules, even the family of elements…
