1. Starter 10/30 Draw the atomic model for Oxygen (O) If you can’t remember how to draw a Bohr diagram, write down all the information you know about oxygen based on the periodic table

2. Atomic Structure Sublevels

3.  Draw the nucleus (label the p + & n 0 )  Draw the correct # of electron levels (# of electron levels = row #)  Fill in the correct # of e - (# of e - in each level matches # of elements in each row) Bohr Diagrams

4. Bohr Model Practice  Calcium  Silver

5. Sublevels  we can divide electron levels into regions called sublevels sublevelmaximum # of e - s2s2s2s2 p6p6p6p6 d10 f14 2 - 1 st energy level 8 - 2 nd energy level 18 – 3 rd energy level 32 – 4 th energy level

7.  How many of each sublevel are filled with: Chlorine’s electrons? Chlorine’s electrons? 3 s 3 s 1.5 p 1.5 p 0 d 0 d 0 f 0 f

8.  How many of each sublevel are filled with: Iodine’s electrons? Iodine’s electrons? 5 s 5 s 3.5 p 3.5 p 2 d 2 d 0 f 0 f

9.  How many of each sublevel are filled with: Calcium’s electrons? Calcium’s electrons? 4 s 4 s 2 p 2 p 0 d 0 d 0 f 0 f

10. Orbitals  each sublevel is broken into orbitals  each orbital can hold a maximum of 2 electrons  orbital- a 3D region around the nucleus that has a high probability of holding electrons

11. Number of Orbitals sublevelmax # e-# orbitals s21s21s21s21 p63p63p63p63 d105 f147

12. One s orbital  spherical

13. Three p orbitals  dumbbell-shaped

14. Five d orbitals

15. Seven f orbitals
