  1. What are the Three Principle Particals that compose an Atom and their Charges
    • 1. Protons (positively charged)
    • 2. Neutrons (uncharged)
    • 3. Electrons (negatively charged)
  2. Where are the Three Principle Particals that compose an Atom
    • 1. Protons found within the nucleus of the Atom (positively charged)
    • 2. Neutrons found within the nucleus of the Atom (uncharged)
    • 3. Electrons orbit the nucleus of the Atom (negatively charged)
  3. What is the Mass of a Protone
    One Atomic Mass Unit
  4. What is the Mass of a Neutron
    One Atomic Mass Unit
  5. What is the Mass of an Electron
    Almost Weightless
  6. The Atomic number of an Atom is based on what
    The Number of Protons
  7. What contribute to the Atomic Mass or Weight of an Atom
    • The Sum of the Number of Protons or (Atomic Number) PLUS the Number of Neutrons
    • AMW = # of Protons or Atomic # (+) # of Neutrons
  8. What ar the Six Elements that compose 98% of the Weight of Living Organiams
    • Carbon (C)
    • Hydrogen (H)
    • Nitrogen (N)
    • Oxygen (O)
    • Phosphorus (P)
    • Sulfur (S)
  9. What is an Isotope
    • Seen when a Atom has the Same Number of Protons in the nuclues but Different Number of Neutrons Resulting in;
    • C12 , C13, C14
    • All Carbone but have different Atomic Mass
  10. How many Shells will a Atome have, Name them and how many max Electrons
    • 3 Outter Shells
    • K, 2 max Electroms
    • L, 8 max Electrons
    • M, 8 max Electrons
  11. Define Inert
    Atoms with a Full Outter Shell
  12. Define Reactive
    • Atom that does Not have a Full Outer Shell
    • Therefore it will interact with other Atoms to fill the shell
  13. Define Neutral Atom
    The number of Protrons are Equal to the number of Electrons
  14. Define Chemical Bond
    When reactive atoms Collide into each other
  15. Define Ionic Bonds
    • The Transfer of Gain of Electrons
    • Formed when Electrons from the outter shell of Atom A, is Transfered to the outer shell of Atom B. Therefore each Atom A and B now have Lost or Gained an Electron, leaving the polarity of Protons to Electrons unequal, now they are called Ions. Atoms who lost electron is Positively Charged and Atom who Gained electron is Negatively Charged.
  16. What are Covalent Bonds and how are they formed
    • Formed when Two Atoms Share Electrons to fill their outter shell.
    • Resulting in two happy Atoms.
  17. In a Chemical Reaction what is a Reactent
    • The Substances that one Starts with
    • S + O2 ............SO2
  18. In a Chemical Reaction what is the Product
    • The substance that Results from the reaction
    • S + O2 ............SO2
  19. What is an Oxidation Reaction
    Remenber OIL RIG
    The loss of Electrons or Hydrogen Atoms
  20. What is a Reduction Reaction
    Remenber OIL RIG
    The Gain of Electrons or Hydrogen Atoms
  21. In the below reaction is Na being Reduced or Oxidized
    Na + CI............. Na+ CI-
    OIL RIG
    Na Lose an Electron therefore it is Oxidized
  22. In the below reaction is CI being Reduced or Oxidized
    Na + CI............. Na+ CI-
    OIL RIG
    CI Gains an Electron therefore it is Reduced
  23. Define Ions
    Molecules with an Eletrical Charge due to the Gain or Lose of Electrons
  24. What is a Cation
    A Positively Charged Ione
  25. What is a Anion
    A Negatively Charged Ion
  26. The Name for Equal Sharing of Electrons
    Non-Polar Covalent Bond
  27. The Name for Unequal Sharing of Electrons
    Polar Covalent Bonds
  28. What gives an Element its Identity
    Only the Atomic Number/Number of Protons
  29. What is the Outter Most Shell of anAtom that has electrons called
    Valence Shell
  30. What does the Vertical Comumn of the Periodic Tabel tell you
    How many Electrons are on the Atoms Valence Shell
  31. The Horizontal Row of the Periodic Table tells you what
    How many Shell the Atoms has
  32. When does an Atom become an Ion
    When it either Gains or Looses Electrons
  33. Which Bond is stronger Ionic or Covalent
    Covalent
  34. Attraction for Electrons by a Necleus is is called
    Electronegativity, which also determins the type of Covalent Bond
