Today’s Game Plan
Topic: Bohr ModelEssential Questions: What does an atoms structure look like?
How are electrons configured in atoms?
Subatomic Particles Review
What are subatomic particles?
How do we determine the number of Subatomic Particles in an atom?
The parts that make up an atom. ◦ PEN: Protons, Electron, Neutrons
Atomic Number= # of protons & electrons (in a neutral atom)
Atomic Mass= #protons + # neutrons
Mass
# Protons
What is the Bohr Model?

What is the Bohr Model?
Bohr’s Model was used to explain the energy of atoms
Only works for Hydrogen, but is good visualization for atomic structure
P+: 1 E-: 1N0:1-1= 0

Constructing a Bohr Model
LET’S PRACTICE WITH NITROGEN!
How do we make a Bohr Model?
1. Determine # protons & Neutron draw them in inner circle
2. Determine # Electrons place in energy levels as follows 1st energy level= 2e- max 2nd energy level= 8e- max 3rd energy level= 18e- max

Let’s Talk About Valence Electrons
How do valence electrons effect an elements reactivity?
What are Valence Electrons?
What’s the Octet Rule?
Electrons in the outer most shell◦ Determine elements chemical
properties
Atoms gain, lose, or share electrons in order to have 8 valence electrons
