Week: 18
Welcome Back!
Topic: Chemical Interactions: Chemical Bonding (Covalent Bonds)
Students will be able to:
Draw the Bohr’s electron shell diagram and the electron dot formula.
State what holds covalently bonded atoms together.
Identify the properties of molecular compounds.
Explain how unequal sharing of electrons occurs and how it affects molecules.
Essential Question:
What happens when we share something with our friend?
This week the 8th graders will work with the outer shell of elements and create covalent bonds to understand the concept of electron sharing. They will use the electron dot formula to create these bonds and prove mathematically that they work.
Key Terms:
covalent bond
molecule
double & triple bond
molecular compound
polar & non-polar bonds
Differentiated Instruction:
finding patterns
predicting
observing
interpreting data
Upcoming:
Exploring ionic bonding and why these valence electrons are given up or taken.
