Chemicals

• What are they??
• There is nothing you can touch or hold that is

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.

18

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
  reproducible
• Propose theory

22
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

23
Element Names and Symbols

• Element Ele
• name symbol
• 1 or 2 letters (occasionally 3)
• 1st letter is capitalized, 2nd letter is lower
  case.

24
Nomenclature

• Learn the names and symbols of the elements.
• 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
