Transcript of Summing up Electron Configuration What is it :

Date: 11-15-13 - Test next WednesdayDay Plan: 1) Review / Homework

2) Project Conclusion Opener: (Sublevel Notation Problems)

1. The region outside the nucleus where an electron can most probably be found is thea. electron configuration. c. s sublevel.b. quantum. d. electron cloud

2. A spherical electron cloud surrounding an atomic nucleus would best representa. an s orbital. c. a combination of px and py orbitals.b. a px orbital. d. a combination of an s and a px orbital.

3. An orbital that could never exist according to the quantum (Sublevel Notation) description of the atom is

a. 3d. c. 6d.b. 8s. d. 6p.

4. The number of possible orbital shapes for the third energy level is

a. 1. c. 3.b. 2. d. 4.

5. How many electrons are needed to completely fill the fourth energy level?

a. 8 c. 32b. 18 d. 40

• Summing up Electron Configuration• What is it : – Likely hood of where electrons can be found around the atom

• What is Important about it: – Energy Levels increase as atoms get bigger– Energy is important for how atoms bond together– 7 Energy levels in the periodic table (In order of Periods)

HOW MANY ORBITALS PER LEVEL

• Ways to show electron configuration – of Carbon • 1) Bohr Model Bohr Notation

• 2) Sublevel Notation

• 3) Orbital Spin Notation

Butters Rocks• 4) Lewis Dot Structure

• What am I doing today? 1) Periodic Table Activity

a) Make Sure you have a rubric – 1 per personb) Turn in project by the windowc) Put each group members rubric on top of the projectd) Make sure to do the partner evaluation e) Turn in conclusion Questions on a separate side

f) When you are done finish your vocabulary 10 – words
