  verifiable excuse).
    Supervised Tutoring Referral
• Students are referred to enroll in the following supervised
  tutoring courses if the service indicated will assist them in
  achieving or reinforcing the learning objectives of this
      IDS 198, Supervised Tutoring to receive tutoring in general
      computer applications in the Tech Mall;

      English 198W, Supervised Tutoring for assistance in the English
      Writing Center (Room 70-119); and/or

      IDS 198T, Supervised Tutoring to receive one-on-one tutoring in
      academic subjects in the Tutoring Center (Room 70-229, 644-
 Regular attendance is mandatory - you may
  be dropped if you miss more than 6 hours of
  class (1 week).

 You will not be dropped if you have not
  checked out of the laboratory! This means
  you may receive an F!!!!
Academic Integrity Policy
 All work must be your own!
 Calculators will not contain cheat
 See college catalog for more
  information, as well as the Grossmont
  Chemistry Departments Academic
  integrity Policy.
           Disabled Students
• Students with disabilities who may need
  accommodations in this class are encouraged to
  notify the instructor and contact Disabled Student
  Programs & Services (DSPS) early in the semester
  so that reasonable accommodations may be
  implemented as soon as possible. Students may
  contact DSP&S in person in Room 110 or by
  telephone at (619) 644-7112 or (619) 644-7119
  (TTY for deaf).
        Additional Information:
• The maximum number of times a student may
  enroll in the same credit course is three times.
   – A student, through a combination of substandard grades (D or
     F) and withdrawals on their student record, may only take a
     class three times.
   – If a student, through a combination of substandard grades (D
     or F) and withdrawals, wishes to take a class for the fourth
     time, they must submit a petition to the Admissions and
     Records Office. Petitions will only be approved based on
     extenuating circumstances.
   – Military Withdrawals do not count in terms of repetition
     restrictions, nor do withdrawals that occur due to fire or flood
        Computer Tutorials
These tutorials are available to anyone who
registers for Chemistry 120T. They are useful
study tools and completion of 85% of these drills
will earn 1 unit of credit. Talk to your instructor
for more information on the tutorial course.

– These tutorial are able to be done at home a
  small portion of this work is required to be
  done on Campus

             Fabulous Learning Tool
 How Many Classes Are Too Many?
• For example: I am taking 16 units this
  semester as a freshmen at a community

  Spanish            4 Credits
  Calculus 1         4 credits
  Chemistry 120      4 Credits
  Psychology         4 credits
  How Many Classes Are Too Many,
         Can I handle the work load?
• Each instructors is convinced there class is the
  most essential and deserves your full effort.
• Most classes require 12-15 hrs per week of study
  time. (this is why 12 units is considered full time
  as a student)
   – Science courses tend to be more intense and require
     additional time.
• Thus the schedule mentioned earlier, requires a
  minimum of 48 hours of study per week plus class
  How Many Classes Are Too Many,
• This calculation does not take into account a work
  schedule and family obligations.
• If you want to succeed in your classes, do not
  overload your schedule, especially with science
• Every student feels they are the exception and can
  handle the extra school load in order to achieve
  some idealistic graduation date. Be realistic about
  your abilities and time obligations.
         Studying Chemistry
• Be curious
• Learn vocabulary (and nomenclature)
• Keep current in the class. Don’t wait for a
• Form a study group
• Do problems again and again!!
Chemistry: An Introduction

         Chapter 1
• What are they??

• There is nothing you can touch or hold that
  is not made of chemicals.
         What is Chemistry?
• Chemistry is the science of the properties,
  composition, and behavior of materials.

• Chemistry is the science concerned with
  describing and explaining the different
  forms of matter and the chemical reactions
  or matter.
       Branches of Chemistry
• Applied Chemistry - the search for and
  isolation of useful materials.

• Theoretical Chemistry - Provides a
  chemical view of nature and explanations of
  natural processes.
Chemistry is the Central Science
           Scientific Thinking
• Make observation
• Gather facts (more observations)
• Propose hypothesis (tentative explanation)
• Test hypothesis (perform experiment)
• Gather more facts and generate new hypothesis
• Re-test new hypothesis - Show that results are
• Propose theory
        From Scientific Model
• Hypothesis- a tentative explanation for an
  observation. (An unproven theory)

• Experiments – tests that look for observable
  predictions of a hypothesis or theory

• Laws – brief statements that summarizes past
  observations and predict future ones

• Theories or Models - unifying explanation for a
  set of observations, facts, and laws
   Element Names and Symbols
• Element                 Ele
• name                   symbol
•                        1 or 2 letters
                         (occasionally 3)
• 1st letter is capitalized, 2nd letter is lower
• Learn the names and symbols of the

• You must know 1st 36 elements + Rb,Sr, Cs,
  Ba, Ra, Zr, Ag, Cd, Sn, Sb, Te, I, Xe, Pt,
  Au, Hg, Pb, Bi, Rn, U
