  1. Chemistry Review 1 Atomic Structure

  2. What should you study? • VOCAB, VOCAB, VOCAB (Auto Pilot, flash cards) • Basic Concepts and Ideas (review book) • Regents type questions with solutions (school Island)

  3. Atom Alpha Particle Atomic mass Mass number Atomic mass unit Atomic number Beta particle Compound Electron nucleus Electron configuration Electron dot diagram Electron shells Element Empty space concept Excited state Ground state Ion Isotope neutron Today’s vocab

  4. Orbital Principal energy level Proton Spectral lines Subatomic particle Valence electron wave mechanical model Today’s vocab

  5. Smallest particle of an element that represents its physical and chemical properties

  6. Atom

  7. Subatomic particle with a charge of -1 and a mass of 1/1836 of an amu; orbits the nucleus

  8. electron

  9. Substance that can be decomposed by a chemical change; composed of 2 or more elements chemically combined in a definite ratio

  10. compound

  11. An atom with one or more electrons not in the ground state or lowest energy level

  12. Excited state

  13. Atoms with the same number of protons but a different number of neutrons

  14. Isotopes

  15. The name for the superscript 4 in

  16. Mass number

  17. Name given to the outermost principal energy level

  18. Valence level

  19. How many shells in the following atom?

  20. Four

  21. How many valence electrons in the following atom?

  22. one

  23. Region of most probable location of electrons in an atom

  24. orbital

  25. Subatomic particle located in the nucleus with a charge of +1; determines the identity of the element

  26. proton

  27. Weighted average of all the isotopic masses of an element

  28. Atomic mass

  29. 1/12 of the mass of a carbon-12 atom

  30. amu or atomic mass unit

  31. Concepts Atoms: What are they made of? How are they put together? How do we know?

  32. Parts • Nucleus has most of mass (protons: +1, neutrons: 0) • Electrons (-, lightweight) orbit in shells

  33. Rutherford’s model

  34. Bohr Model

  35. Nuclear Notations

  36. Electron configurations

  37. Electron dot structures • As would likely make 3 covalent bonds
