Side A ------ Side B
What is the basic unit of matter? (pg 35) Definition Card!!!! ------ The Atom (pg 35)
How many atoms would it take to make a row of about 1 cm ? (page 35) ------ 100 million (page 35)
What makes up an atom? (page 35) ------ The subatomic particles, Protons, Neutrons, and Electrons (page 35)
Properties of sub atomic particles? (page 35) ------ Protons - Positively charged                  Same mass as neutronNeutrons - Neutrally charged, no charge                  Same mass as ProtonElectrons - Negatively charged                   1/1840 of the mass of a proton or                         neutron
Properties of atoms? (Page 35) ------ 1. They have equal #'s of protons and electrons.2. They are neutral charged because the charges cancel each other out
What is a chemical element? (page 36) ------ A pure substance, that consists entirely of one type of atom. (page 36)The # of protons (Atomic #) determines the type of element (page 36)
About how many elements are known? (page 36) ------ More then 100.
Isotopes properties (page 36) ------ Atoms of the same element that differ in the # of neutrons. (page 36)All have the same chemical properties b/c they have the same # of electrons (page 36)
The mass # (page 36) ------ The # of protons + the # of neutrons in an atom.
Radioactive Isotopes (page 36) ------ Elements where The nuclei break up over time, they become a different element and give off something like a photon, electron, or alpha particle.
Chemical Compounds? (page 37) ------ Substance formed by the chemical combination of two or more elements in definite proportions. (page 37)Physical and chemical properties differ from the elements that make them up.Example: H2O very different from hydrogen and oxygen. (page 37)
Chemical Bonds? (Page 38) ------ Hold  atoms together.Electrons that can form bonds are called valence electrons.3 Types-Ionic-Covalent- Van Der Waals                                         
Ionic (page 38) ------ Electron transferred from one element to another.Ions are formed "charged atom"Ions attract and bond. (Page 38)
Covalent (Page 38) ------ Electrons shared between two elements. # of electrons shared = # of electron pairs shared.Results in a molecule.(Page 38)
Van Der Waals. (Page 39) ------ Attractions between molecules.  (Page 39)
