L EARNING T ARGETS I can use the periodic table to create Bohr models and Lewis Dot Structures for any of the first 20 elements. (Level 4) I can explain how the light emitted (put out) by an energized hydrogen atom helped Bohr figure out his model

F LAME T EST D EMO As you watch the demonstration, try to answer this question: What makes different colors in fireworks?

A TOMIC S TRUCTURE N OTES 11 Na Sodium 23.0 Atomic Number Symbol Name Atomic Mass Unit (amu)

A TOMIC S TRUCTURE N OTES TermWhat it tells youExample Name Symbol Atomic Number Atomic Mass Unit (amu) The name of the element The abbreviation associated with the name Number of protons Number of electrons in single atom Number of protons + Number of neutrons Na Sodium Then how many neutrons does Sodium have?

F LAME T EST D EMO Why is Lithium pinkish purple? Why is Sodium green? Each element in the periodic table has electrons that are “energized” by the flame When these particles are “energized” they jump to a higher energy level As they come back to their original energy level, they emit different colors!!!

S ET U P C ORNELL N OTES Title: Valence Electrons

V ALENCE E LECTRONS Valence electrons are the outer most electrons on a atom. The last ring that has an electron Valence electrons determine what that element will react with, do, look like, etc. With a full valence electron shell, the atoms are stable and happy.....noble gas! Octet Rule: atoms want a full level of electrons (typically 8) Exception is Helium (has 2 in outer shell)
