What is Chemistry? What do chemists do?

What is Chemistry? The study of how atoms combine into molecules (and larger structures). What do chemists do? Chemists make and study molecules.

What are the most serious problems in the country? Chemistry. What good is it, anyway?

Thinking like a chemist: First class assignment How many golf balls will fit in this room? You have 5 minutes.

Diameter of a golf ball = 1.68 in

What if the golf balls were: too small to touch? individually invisible?

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-Elements Molecules-Compounds These are the chemical elements. The smallest particles of which are ATOMS. Combinations of elements make COMPOUNDS. The smallest particles of which are MOLECULES.
