Presentation Transcript

  1. Write the atomic # & atomic mass for one of the following elements: http://www.yeousch.com/community/threads/science-jokes-for-the-fellow-nerdlings.7127/

  2. Agenda • Energy Levels • Bohr Diagrams • Review Game

  3. The most frequently used models… • Two atomic models are used most frequently: • Schrödinger • Bohr • Schrodinger’s is the most accurate, but Bohr’s is more simplistic • Bohr’s model is accurate for simple atoms

  4. Electron Energy • Bohr discovered that e- can be found at different energy levels, but can’t be found between energy levels. • The energy level the e- is usually found in is known as the ground state.

  5. Excited e- • If an e- gains energy, it can move to another energy level • The e- is now in the excited state • Eventually the e- will loose its energy and return back to the ground state. • When this happens light is emitted • Different elements give off different colors (fireworks)

  6. Energy and the Atomic Model • Using this information about energy, Bohr created his own atomic model • e- closest to the nucleus have the least amount of energy • e- farthest from the nucleus have the most

  7. Energy Levels (Shells) • Bohr labeled these energy levels as; • k, l, m, n, o, p, q • Shell k can only have 2 e- • The rest can have 8 e- • The lower energy levels must be at capacity before e- can move to higher energy levels

  8. What this means… • If you had 16 e- • You can do this for every element on the periodic table • This led to the Bohr Diagram http://chemistryiseasy.com/

  9. Steps to create a Bohr Diagram • Find the number of protons. • Find the number of neutrons. • Find the number of electrons. • Draw a circle to represent the nucleus. • Insert the number of protons and neutrons. • Draw enough energy shells to house all of the electrons.

  10. Examples

  11. Review Game • Reviewing Atomic Structure and Bohr Diagram practice

  12. First things first… • Wednesday is the start of Baseball Playoffs! http://ladylovespinstripes.com/

  13. Rules of Baseball Science • You will be split into two teams • Each team will send a player “to bat” • The batting player has the option of: • Single • Double • Triple • Homerun • If you miss the question – out • If you take more than 10s to answer - strike
