  14. Business I • Class meetings: • Lecture MWF here • Lab once a week in Physical Sciences Bldg. • Recitation once a week in Physical Sci. Bldg. • NO LABS or RECITATIONS this week- they start Monday • Class Rules- Syllabus (go over on Friday)

  15. Business II Classroom Rules • 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

  16. Business III • Homework: • OWL Electronic Homework System • First assignments due in one week • Gateway Quizzes • First 20 elements • Tables of common ions

  17. 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

  18. To Begin • Why is chemistry hard?

  19. To Begin • 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.

  20. To Begin • Why is chemistry useful?

  21. To Begin • Why is chemistry useful? • 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.

  22. Chapter 1 • Review- read it and know it. • Homework on it starting today.

  23. The Periodic Table is Your Friend

  24. 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)

  25. Atoms-ElementsMolecules-Compounds • These are the chemical elements. • The smallest particles of which • are ATOMS. • Combinations of elements makeCOMPOUNDS. • The smallest particles of whichare MOLECULES.

  26. Classification of Matter

  27. Classification of Matter • Some to try: • Air _______________ • Water _______________ • Tea _______________ • Cookie _______________ • Aluminum foil _____________ • Milk _____________ • Pen ink _____________ • Soda _____________ Find all the pure elements in the room.
