Title: What are atoms, elements, molecules, and compounds?


1
What are atoms, elements, molecules, and
compounds?
  • SPS2 Students will explore the nature of matter.

2
Draw the picture below in your notes
  • Write and answer the following
  • What are the atom(s)?
  • What are the elements?
  • What is the molecule?

3
Chemistry study of matter and how it behaves
4
Classification of Matter
  • Atom
  • Element
  • Molecule
  • Compound

5
Atom smallest piece of matter
  • 110 different kinds of atoms
  • Combine to make all the forms of matter in
    universe
  • Too small to see but can see with the most
    POWERFUL microscopes

6
The Atom
Part Charge
Electron Negative (-)
Proton Positive ()
Neutron None (X)
7
Element a pure substance
  • Groups of all the same kind of atoms

8
Molecule two or more atoms joined together
Diatomic Molecules two of the same
atoms H2 Cl2 O2
9
Compound groups of the same kind of molecules

An Overview of the LINCS Strategy
  • Step 1 List the parts
  • Step 2 Identify a Reminding Word
  • Step 3 Note a LINCing Story
  • Step 4 Create a LINCing Picture
  • Step 5 Self-test

11
  • Creating LINCS Table
  • Keep in mind
  • That you must go in order
  • Box 1
  • Box 2
  • Box 3
  • Box 4
  • Box 5

12
Creating LINCS Table
Box 1. Write the word to be learned on the top
half. Then circle it.

Box 2. Write the parts of the definition you
need to remember. Underline key terms.
A pure substance.

Creating LINCS Table
Box 4. Write the LINCing Story. Using the
reminding word (Box 3) and the key words from
definition (Box 2).
A pure substance.

TOD
  • Create a colored poster of one of your LINX
    tables.
  • We will share at the end of class.

Activator
  • What do the prefixes mean
  • Homo
  • Hetero

20
Mixture combination of materials
  • Not chemically joined
  • Can be separated physically
  • Sorted, filtered, evaporation

21
2 kinds of mixtures
  • Homogenous same throughout
  • Ex tea, kool-aid, air
  • Heterogeneous not the same throughout
  • ex salad, saltpepper

22
Homogeneous mixture same
23
Heterogeneous not same

5. Dirt
6. Pepsi
7. Silver (Ag)
8. Toothpaste (Na2HPO4)
9. A burrito
10. Italian Dressing
11. Chicken Soup
12. Lemonade
Column A lists a substance. In Column B, list
whether the substance is an element (E), a
compound (C), a Heterogeneous Mixture (HM), or a
Solution (S). (Remember a solution is a
homogeneous mixture.)
