Bell Ringer 09.07.11•Which of the following represents an
organic molecule?▫A. CuSO4 H2O▫B. C12H22O11
▫C. AgNO3
▫D. H2O
Atom•Smallest basic unit of ______.
•What else have we identified as a basic unit of structure and function?
Element•Type of atom•Can’t be broken down into a simpler
substance•Identified by number of ______•How can we identify the number
Of protons, neutrons and electronsFrom this picture?
Elements•Carbon, Oxygen, Nitrogen and Hydrogen=96% of human body’s mass
Bohr Model
Draw a hydrogen, oxygen, and carbon atom. Check your book to see how many protons, neutrons, and electrons to include.
Ions and Isotopes•________-same number of protons (same
element) different number of neutrons (different mass)▫Ex: Carbon-14
• ________-atom or group of atoms with a positive or negative charge
Ex: Na+
Is this a cation or anion? What’s the difference?
Compounds•Different elements bonded together in a
certain ratio•Can be _______ or ________•Examples?
Compounds•Compounds often have different ______
than the elements that compose them.•Example: water
Chemical Bonds•Chemical bonds form between ______•Different types: Ionic and Covalent
Assignment•In your group, create a diagram showing
the differences between Ionic and Covalent bonds.
•Use your textbook and the article provided for information
•Include:▫Characteristics▫Pictures/Drawings▫Examples
