Mickey Mouse Molecule

Step One

• Color the pieces – the nuclei need to be the same color as their respective atoms. All atoms of the same element should be the same color.

• All electrons should be colored the same color. Make it a totally different color than what you have used thus far.

Page 3: Mickey Mouse Molecule. Step One Color the pieces – the nuclei need to be the same color as their respective atoms. All atoms of the same element should

Step Two

• Cut out the pieces and… Match the nuclei to their respective atoms.Match the electrons to their respective atoms.

Call me over and get your worked checked before you proceed to gluing!!!

Page 4: Mickey Mouse Molecule. Step One Color the pieces – the nuclei need to be the same color as their respective atoms. All atoms of the same element should

Step Three

• Glue the nuclei and electrons to their respective atoms.

• DO NOT CONNECT ATOMS YET!

• Locate a sheet of notebook paper.

Step Four

• How many electrons are in oxygen’s outer shell?

• An atom needs to have its outermost electron shell FULL in order to be stable. – Is oxygen stable?

BONDING

• The oxygen atom is going to SHARE hydrogen’s electrons.

• This is called a COVALENT BOND.• Covalent bonds are strong, but ionic bonds are

stronger!

Step Five

• Stabilize your oxygen atom!

What do you notice about this molecule?

• Unequal sizes of atoms• Unequal sharing of

electrons• Results in a POLAR

COVALENT BOND• “ears” have _____

charge• “head” has

_______charge• Label your molecule!

So what?

Hydrogen bonding!

Hydrogen Bonding

• The weakest type of bond, more of an attraction…

• But incredibly powerful!!!

• Bottle capped with cloth – it overcame the force of gravity!

Because water molecules are sticky…

• ADHESION – stick to other things• COHESION – stick together• SURFACE TENSION• STAYS A LIQUID OVER A HUGE TEMPERATURE

RANGE – moderates temperature…• UNIVERSAL SOLVENT – dissolves things!
