Starter 10/30

• Draw the atomic model for Oxygen (O)
• If you cant 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
Bohr Diagrams

• Draw the nucleus (label the p n0)
• 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)

4
Bohr Model Practice

• Calcium
• Silver

5
Sublevels

• we can divide electron levels into regions called
  sublevels
• sublevel maximum of e-
• s 2
• p 6
• d 10
• f 14

2 - 1st energy level
8 - 2nd energy level
18 3rd energy level
32 4th energy level

d block
p block
f block
7

• How many of each sublevel are filled with
• Chlorines electrons?
• 3 s
• 1.5 p
• 0 d
• 0 f

8

• How many of each sublevel are filled with
• Iodines electrons?
• 5 s
• 3.5 p
• 2 d
• 0 f

9

• How many of each sublevel are filled with
• Calciums electrons?
• 4 s
• 2 p
• 0 d
• 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

• sublevel max e- orbitals
• s 2 1
• p 6 3
• d 10 5
• f 14 7

12
One s orbital

• spherical

13
Three p orbitals

• dumbbell-shaped

14
Five d orbitals
15
Seven f orbitals
