Starter 1030 Draw the atomic model for Oxygen

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

Atomic Structure Sublevels

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

Bohr Model Practice Ø Calcium Ø Silver

Sublevels Ø we can divide electron levels into regions called sublevels sublevel maximum # of e 2 - 1 st energy level s 2 8 - 2 nd energy level p 6 rd energy level 18 – 3 d 10 32 – 4 th energy level f 14

s block d block f block p block

Ø How many of each sublevel l are filled with: Chlorine’s electrons? 3 s 1. 5 p 0 d 0 f

Ø How many of each sublevel l are filled with: Iodine’s electrons? 5 s 3. 5 p 2 d 0 f

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

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

Number of Orbitals sublevel s p d f max # e- # orbitals 2 1 6 3 10 5 14 7

One s orbital Ø spherical

Three p orbitals Ø dumbbell-shaped

Five d orbitals

Seven f orbitals
