Take HandoutsDon’t sit in last four rows
What is Chemistry?The study of how atoms combine into
molecules (and larger structures).
What do chemists do?Chemists make and study molecules.
Thinking like a chemist:First class assignment
How many golf balls will fit in this room?
You have 5 minutes.
Business I
• Class meetings:– Lecture MWF here– Lab once a week in Physical Sciences Bldg.
• NO LABS this week- they start Monday
• Class Rules- Syllabus (go over on Friday)
• Course Materials: Text, Labs, Goggles, Clickers
Business II
• Be here every single day
• Be here on time
• Don’t sit in back
• Don’t talk when I’m talking
• Don’t let me talk when you’re talking
• It’s ok to get up and wander
Classroom Rules
Business III
• Homework:– OWL Electronic Homework System– First assignments due in one week
Mastery Based: Work till you get it
How to do well
• Sit in front
• Read text chapter before and after covering
• Do homework early and often
• Avail yourself of help:– me– chemistry tutors (times given next week)
• Keep up with material
• Ask questions
Why is chemistry hard?• Atoms are really small.
• About 100 types of atoms (each a chemical element).
• Matter is made of atoms, mostly connected together in molecules and larger structures- infinite variety of combinations.
• Lots of math.

Chapter 1: Matter and Measurement
• Atoms and Elements• Molecules and Compounds• Classification of Matter• Properties of Matter and Measurement
– Temperature– Mass– Volume
• Unit Analysis Calculations (recitation)
Atoms-ElementsMolecules-Compounds
•These are the chemical elements.•The smallest particles of whichare ATOMS.
•Combinations of elements makeCOMPOUNDS.•The smallest particles of whichare MOLECULES.
