  1. ATOMIC NUMBER
    DEFINES THE SEQUENCE IN TABLE AND NUMBERED ACCORDING TO COMPOSITION: GAS/LIQUID/SOLID
  2. WHICH ELEMENT PROVIDES ENERGY FOR THE HUMAN BODY
    OXYGEN
  3. ADDING A PROTON TO NUCLEUS OF AN ELEMENT
    • RESULTS IN A NEW ATOM
    • ATOM # +1
    • NEW ION IS POSITIVELY CHARGES
  4. IF A PHOTON STRIKES AN ELECTRON IN THE GROUND STATE WITHIN A HYDROGEN ATOM
    THE ELECTRON MAY BE BOOSTED TO A HIGHER ENERGY LEVEL IF THE PHOTON HAS THE RIGHT AMOUNT OF ENERGY
  5. VALENCE ELECTRONS
    • ELECTRONS IN OUTER SHELL OF ATOM
    • LOOSELY BOUND
    • CRITICAL IN THE BOUNDING PROCESS
  6. VALENCE
    NUMBER OF ELECTRONS IN OUTERSHELL
  7. ELECTRONS CAN BE
    LOST, GAINED, BUT NOT CREATED
  8. SODIUM AND CHLORINE
    FORMS A CRYSTAL LATTICE HELD TOGETHER BY HYDROGEN BONDS
  9. CHEMICAL REACTIONS

    ELEMENTS WITH LOWER ATOMIC NUMBERS ARE
    MORE REACTIVE
  10. ELEMENTS
    CHEMICAL SUBSTANCES THAT CANNOT BE BROKEN DOWN ANY FURTHER
  11. ATOMS
    THE SMALLEST PARTICLE THAT RETAINS ITS CHEMICAL IDENTITY.
  12. MOLECULES
    COLLECTION OF 2 OR MORE ATOMS BOUND TOGETHER
  13. PERIODIC TABLE
    SYSTEMATIC ORGANIZATION OF ALL KNOWN ELEMENTS
  14. STRUCTURE OF THE ATOM
    • ELECTRON
    • NUCLEUS
    • PROTON
    • NEUTRON
    • ION
  15. ELECTRON
    ATOMIC PARTICLE WITH LOW MASS NEGATIVE CHARGE
  16. NUCLEUS
    THE SMALL, MASSIVE CENTRAL PART OF THE ATOM
  17. PROTON
    POSITIVE CHARGED NUCLEAR PARTICLE
  18. NEUTRON
    • SUB ATOM PARTICLE (IN NUCLEUS)
    • NO NET ELECTRICAL CHARGE
  19. ION
    AN ELECTRICALLY CHARGED ATOM
  20. PHOTONS
    A PARTICLE LIKE UNIT OF LIGHT EMITTED OR ABSORBED BY AN ATOM WHEN AN ELECTRICALLY CHARGED ELECTRON CHANGES
  21. GROUND STATE
    LOWEST ENERGY STATE
  22. EXCITED STATE
    ELEVATED ENERGY ABOVE BASELINE
  23. SPECTROSCOPY
    THE STUDY OF THE INTERACTION BETWEEN MATTER & ENERGY

    THE STUDY OF LIGHT AS ITS DISPERSED BY A PRISM
  24. CHEMICAL BONDING
    THE PROCESS BY WHICH 2 OR MORE ATOMS COMBINE
  25. IONIC BONDS
    CHEMICAL BONDS IN WHICH THE ELECTRICAL FORCE BETWEEN TWO OPPOSITELY CHARGED IONS HOLD THE ATOMS TOGETHER
  26. CONVALENT BONDS
    IN WELL DEFINED CLUSTERS OF ATOMS WHERE THE ELECTRON PAIR ARE SHARED
  27. POLARIZATION
    CLUSTERS OF ATOMS THAT ARRANGE IN SUCH A WAY AS TO HAVE REGIONS OF POSITIVE CHARGE AND NEGATIVE CHARGE
  28. STATES OF MATTER
    • GAS
    • PLASMA
    • LIQUID
    • SOLID
  29. CHEMICAL REATIONS
    PROCESS BY WHICH ATOMS COMBINE OR SEPARATE BY REARRANGING ELECTRONS
  30. 2 TYPES OF CHEMICAL REACTIONS
    EXOTHERMIC - ENERGY IS RELEASED IN THE FORM OF HEAT OR LIGHT

    ENDOTHERMIC REACTION - ENERGY (HEAT) IS ABSORBED
