Atomic Structure Review

  1. 1. Atomic Structure Review
  2. 2. Protons <ul><li>Positive Charge </li></ul><ul><li>1 atomic mass unit </li></ul><ul><li>Located in nucleus </li></ul><ul><li>The number never changes </li></ul>
  3. 3. Neutrons <ul><li>No charge </li></ul><ul><li>1 atomic mass unit </li></ul><ul><li>Located in the nucleus </li></ul><ul><li>The number changes based on atomic mass. A new # of neutrons=isotope. </li></ul>
  4. 4. Electrons <ul><li>Have a negative charge </li></ul><ul><li>No mass </li></ul><ul><li>Located outside of the nucleus </li></ul><ul><li>Atoms can gain or lose electrons. </li></ul><ul><li>Gain electrons, negative charge. </li></ul><ul><li>Lose electrons, positive charge. </li></ul>
  5. 5. Determining Atomic Mass <ul><li>Atomic mass is the number of protons and neutrons together. </li></ul><ul><li>Electrons do not count, they have no mass. </li></ul><ul><li>To find the number of neutrons, subtract the atomic number from the atomic mass. </li></ul>
  6. 6. Atomic Number <ul><li>Elements are arranged on the periodic table based upon their atomic number. </li></ul><ul><li>Atomic number tells us the number of protons in an atom. </li></ul><ul><li>The identity of the atom is based on the protons!!!! </li></ul>
  7. 7. Isotopes <ul><li>Know how to find an isotope. </li></ul><ul><li>Be able to calculate the number of neutrons and protons. </li></ul><ul><li>Understand that one atom can have several different isotopes. </li></ul>
  8. 8. Ions <ul><li>Atoms carrying a charge. </li></ul><ul><li>New net charge, either positive or negative. </li></ul><ul><li>Electrons gained=negative </li></ul><ul><li>Electrons lost=positive </li></ul>
  9. 9. Electron Levels <ul><li>S level, fills with 2 electrons </li></ul><ul><li>P level, fills with 6 electrons </li></ul><ul><li>D level, fills with 10 electrons </li></ul>
  10. 10. <ul><li>Be able to identify an atom based on the electron configuration. </li></ul><ul><li>If given an element, be able to give its configuration. </li></ul>
