FPC DAY 63Atomic Structure

WARM UPIn the next available 6 pages, GLUE in

“Atomic Structure and Periodic Table” Learning Target (1 page leave other side blank)

Atomic Structure Notes (2 pages next to each other)

Bohr Model Notes (2 pages next to each other)

LEARNING TARGETS 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

FLAME TEST DEMOAs you watch the demonstration,

try to answer this question: What makes different colors in

fireworks?

Na

SodiumThen how many neutrons does Sodium have?

FLAME TEST DEMOWhy 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!!!

ATOMIC STRUCTURE PRACTICE

Do: Atomic Structure Practice

Use: Your notes and your table group

Ask: Three, before me

Raise: Your hand, if your group has a question

Time: 11 minutes

When Done: Turn into your teacher

SET UP CORNELL NOTES

Title: Valence Electrons

VALENCE ELECTRONS

• 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)
